In the past, I’ve discussed how it’s a good idea to spend your spare time dabbling in entrepreneurship: it fills your time with something that you choose (and thus you enjoy) and sets up a potential long-term revenue stream. I also discussed how I got a side business going myself.

Since then, lots of readers have written to me, asking for ideas on how to start a simple side business. What follows is a list of 50 of those ideas that I’ve collected over the last year or so.

Each of these ideas is very simple to start, and most can be done as a sole proprietorship at first (meaning you don’t have to file any legal documents to get started, though you will want to do that if it starts to take off). Most of these can be done at home in your spare time in your spare space, too.

See if there are any ideas below that fit you well. If you find an idea, seek out a guide on how to get started in that area.

50 Business Ideas

1. Antique refurbishment

This is a perfect side business for people who love antiquing. Take worn-out antiques home with you, invest the time and care needed to transform those old items into something amazing, then resell them at a profit.

2. Auto detailing

Have a meticulous eye for detail and love to get things gleaming clean? Auto detailing is probably a perfect side business for you. In essence, your job is to make cars sparkleinside and out – and many people are quite happy to pay well for this service.

3. Babysitting

Got lots of evenings free? Like kids? Babysitting may be a great side business for you. Keep an eye on multiple children on Friday and Saturday nights and you can earn some solid income.

4. Bed and breakfast

Have some extra space in your home? Turn that extra bedroom into a “bed and breakfast” room. This works particularly well if you have a somewhat older home or live near an area that attracts regular travelers and tourists.

5. Blogging

If you enjoy writing, find a topic you’re passionate about and start a blog on the topic. All you need is a computer, some time, and some energy to consistently write. It can start as a hobby and turn into a business.

6. Cake decorating

Enjoy baking and have a bit of an artistic touch? Learn how to decorate cakes and make them for special events. One of my mother’s old friends does this and makes quite a bit of money on the side.

7. Candle making

Candle making is a great little craft to learn. You can often easily sell the candles at local shops and also through websites like Etsy.com, eBay and more.

8. Candy making

Homemade candies are easier to make than you think and quite popular. Package them in nice little boxes and sell them through a local gift shop. You can get started pretty quickly.

9. Card making

This is another artistic “crafty” angle you can follow. Make greeting/birthday cards from scratch using your own photographs, some blank cards, and a healthy dose of artistic flair. Again, you can sell items like these through a local gift shop or at sites like etsy.com.

10. Catering

If you love to cook, take the “Blondie” route and start a home catering business. Catering is a business that’s perfectly designed to reward those who plan well and can often fit perfectly into weekends, lining up wonderfully opposite a normal workweek.

11. Childcare service

Many states allow people to start up in-home daycares with minimal licensing and paperwork. If you love children and have plenty of time and space at home, this is a perfect business to get into.

12. Cleaning services for businesses

Many businesses and civic institutions have a need for individuals who will provide cleaning services at a low cost outside of business hours. This is a great side business for those who can put in a few hours late at night or on weekends.

13. Collectible trading

If there’s a particular type of collectible that you know a great deal about, you can often make good money as a collectible trader, utilizing tools like eBay and opportunities to find those collectibles in the community. I had some success with this myself with both trading cards and video games in the past.

14. Computer troubleshooting

I had some success with this in the past, though I’ve largely moved away from it now. If you have a knack for fixing computers, this is a good place to start.

15. Consignment buyer

Consignment shops and consignment auctions are often loaded with good deals if you know how to identify them – quite often, you can turn these good deals around and make a nice profit elsewhere. Get started by visiting some consignment shops and critically evaluating the prices on the items there.

16. Cookie making

Much like candy making, homemade cookies can be a great seller. Bake the cookies, package them well, and resell them through a local gift shop. Often, you can find people in your social network who will buy batches from you for special occasions.

17. Dinner preparer

I recently met a woman who earned quite a bit of money as a very part-time chef. Once a week, she would go to someone’s house and prepare a homemade meal for their family, then do all the dishes and cleanup work. This gives the family plenty of together time, while earning the lady some cash in the pocket. If you love to cook, this can be a great opportunity, but you may have to put a lot of work into searching for clients.

18. Event coordinator

Events like family reunions and large parties are often full of busywork that many people simply don’t want to tackle. That can be the perfect place for you to step in and take charge of the planning and coordination.

19. Event DJing

Are you an audiophile? If you have a great sound system and a large selection of music, you’ve already got what you need to hire yourself out as a DJ for various events and receptions. This is a great way to fill an afternoon and evening while also earning some cash in the process.

20. Exercise teacher

Many gymnasiums will trade membership and often a bit more for a person willing and able to teach an exercise class. You can also find people who do not want to go to the gym that you can train from home as a personal trainer. If you’re in good shape, this is a great opportunity to earn some extra money, plus it can often lead to additional income with one-on-one teaching opportunities.

21. Furniture making

If you’re adept at woodworking and have just a bit of basic equipment, it’s easy to get into business making deck furniture. It only requires a few items – a saw, a drill, a sander – and some creativity and passion for working with wood. If you have the tools or just want to turn your hobby into a business this may be a great small business idea for you.

22. Gardening services

I’ve actually had requests from others for people willing to do this, so the demand is out there. To put it simply, some people are willing to pay others to get a vegetable or flower garden started for them in their yard so they can have access to ultra-fresh produce without all the legwork.

23. Handy man services

Skilled at basic home repair? Let people know that they can call you for little repair jobs, like basic plumbing and other things. You’d be amazed at the simple things people are willing to pay others to help them with.

24. Housecleaning

Many people simply don’t enjoy cleaning their homes and are willing to pay a reasonable price to have someone do the work for them. This is a great way to earn extra money in a flexible way, particularly if you have time off during the workweek. Still, you want to be professional and treat it as a business.

25. Interior decorating<

Fascinated by interior design? Have a huge collection of interior design materials around? Many people are quite happy to hire individuals to help them decorate their home – I know, for one, that I have no eye for this type of thing.

26. Jewelry making

If you have a good eye for detail work and a lot of patience, homemade jewelry can be quite profitable. As with other items on this list, there are many opportunities to sell such items through local gift shops or at sites like Etsy.

27. Knitting / crocheting / quilting

Skilled at creating blankets and sweaters? There’s a huge market for these types of items – even better, you can usually make them in your spare time whenever you have it. As always, local shops and places like etsy are great places to go to sell such items.

28. Landscaping services

Willing to mow lawns and trim bushes and trees? Many people are quite happy to pay for such services. Not only is this a great side business for a fit adult, it’s also a great way for a teenager to get a small business started.

29. Meal-to-go preparations

Remember my earlier post about breakfast burritos? Making meals in advance is a great way to save money for yourself – but you can often prepare these for others as well and sell them for a markup. Prepare eight casseroles, for example, then sell six of them to cover your costs, and you’ve got two free dinners for your family (and maybe a bit more). You can grow this by taking orders from others and finding out what they like.

30. Online media consultant

Like participating on messageboards, Facebook, Twitter, and so on? Become an online media consultant and help people promote things. Start small – help local businesses get a presence on Facebook and set them up with Twitter. From there, you can grow to whatever works for you.

31. Pet grooming

Many people loathe bathing their pets and trimming their hair – I know I do. Pet groomers perform these tasks for a small fee – a perfect job for a person who loves dogs and cats.

32. Pet sitting

When people go on trips, they’re often concerned as to what will happen with their pets. That’s where you step in – offer yourself as a safe place to leave their pets, or be willing to go to their home to take care of their pets. It may even go hand in hand with your pet grooming business.

33. Pet walking

Many busy people leave their pets home all day, but realize that those pets really could use a vigorous walk (and an opportunity to relieve themselves) during the day. Pet walking is a great opportunity for exercise, fresh air, and some pocket money if you have free time during each day.

34. Pet yard waste cleanup

For many people in suburban areas, cleaning up pet yard waste is a real hassle – it’s disgusting, for one. Instead of cleaning it up themselves, they might hire someone to do it regularly, two to three times a week. There are several such services in our area, actually.

35. Produce selling

Like to grow vegetables? Focus in on one vegetable and sell the excess to grocery stores and at farmers’ markets. My father does this with tomatoes and earns some solid extra money during the summer months. You can do really well, though, if you can grow things inside during the winter – February fresh tomatoes can sell quite well.

36. Proofreading

Have strong English skills and exceptional grammar? You may have opportunities to work as a proofreader from home. Advertising for this can be difficult – seek out those who might actually be able to use your services and advertise directly to them.

37. Public speaking

If you’re the type of person who can get the attention of a room easily, public speaking might be for you. Take advantage of every public speaking opportunity you can and you’ll be surprised at the opportunities that make themselves available for you.

38. Scrapbook making

Many people dream of having beautiful scrapbooks. They collect all the materials they want in the scrapbooks but never follow through on the actual creation. You can step in here – take their ideas and materials and assemble a scrapbook for them.

39. Senior citizen assistance

Many elderly people need assistance with a wide variety of simple household tasks – cleaning, laundry, and so forth. Many children of elderly people are quite willing to hire someone to help out their parents.

40. Sewing and alterations

My wife is quite handy with a sewing machine and often hems and modifies our children’s clothes. She could easily take this a step further and offer her services to others, doing basic garment repair and modification for a small price on lazy evenings.

41. Social media

Almost everyone uses Facebook, Twitter, Pinterest, etc. these days but did you know that many companies will pay people to help them manage their social media accounts, even part time from home. If you are a social media junky already then this may be a great way to start your own business that you enjoy, simply by playing around on Facebook, Twitter and other social media sites all day. Check outPaidSocialMediaJobs.com for more information on how to get started with this type of business and find companies willing to pay for your services.

42. Soap making and Spa products

Making amazing homemade soaps and other spa products isn’t as hard as you might think – it just takes time and patience. Again, items like these can easily be sold via local gift shops and through websites like Etsy.

43. Teaching music

If you know how to play an instrument (particularly the piano or the guitar) and have patience, you’ve got what you need to teach others how to play. Offer lessons in that instrument to others – this can also be an excellent thing to barter with, too.

44. Toy making

From simple things like sock monkeys to more elaborate things like handcrafted chess sets, many people are willing to pay good money for handcrafted toys that you can easily make at home in your spare time. Again, gift shops are the place to go with items like these.

45. Tutoring

Did you major in a particular topic in college? Do you have patience with children? You likely have what you need to tutor kids in particular subjects. Seek out parents and let them know that you tutor in a particular subject and provide materials for them to share and phone calls will often trickle in. You can get going locally or across the country online.

46. Video preparation services

Many people like to have videos made for special events, such as weddings, or for gifts. This may mean actually taking the video yourself at a special event, or it may mean simply assembling materials and creating a video from those items. Either way, with a well-equipped PC, some taste, and some patience, you can make quite sophisticated video productions at home.

47. Virtual assistant

Many ultra-busy professionals appreciate having someone who can check and answer their email, organize task lists for them, update their calendars, and so on, with minimal interaction. The best part is that you can provide this service from home with a good internet connection.

48. Web site design

Many small businesses in your community could use a very basic web presence to tell others about their business. Quite often, these businesses don’t have a large budget for such things. That’s where you come in – get a bunch of clients from the local community by beating the pavement, create sites for them, and maintain them for a small fee. Get enough businesses and you have a nice side business of your own that doesn’t require a ton of maintenance time.

49. Wedding planner

If you’re one of those people who can’t help but flip through bridal magazines and think about various wedding arrangements in your daydreams, wedding planning might be the perfect thing for you. A great way to get started is to develop a website on the topic, get to know people online, and offer your services throughout the community.

50. Writing/Editing

If you enjoy writing then writing and editing content in your spare time for companies is a great way to earn extra cash. Many website owners and other businesses require content be written or edited for a wide range of topics and uses. Some will even pay you for simple blog posts or comments. This type of business requires no overhead or experience and you can earn a nice income if you can connect with the right companies willing to pay for your writing services. RealWritingJobs.com is a great place to start.

I’m betting the readers have many, many more ideas along these same lines.
