101 Best Side Business Ideas You Can Start While Working a Full-Time Job

21. Presentation Design Consultant.

Yes, even the lowly PowerPoint requires outside consulting every now and then. I know I would happily outsource the visual layout of my presentation decks for work meetings, investor pitches, and lectures. Adam Noar from Presentation Panda is living proof that you can turn your passion for slideshow presentation design into a legit side business.

22. Travel Consultant.

If you love to travel and find yourself randomly searching for airfare sales or browsing Lonely Planet, why not carve out a niche for yourself as a private travel agent? Take my friend, Mark Jackson's lead with what he's doing to build a travel consulting business. Start with word of mouth recommendations from friends who know they can count on you for the cheapest flights, and don't forget to set up an account with Plansify to start getting paid for your travel expertise in your free time.

23. Landing Page Specialist.

If you have a way with words and know how to make the keyword-friendly, beautifully designed, SEO-optimized landing pages, why not charge other companies for your services? Even a short landing page is worth a couple hundred bucks in most cases.

24. Interior Design Consultant.

Someone out there is remodeling their kitchen and needs to know which shade of granite will match best with mahogany flooring. That someone will often be happy to pay you for your advice, especially if you’re the kind of person that subscribes to websites like Contemporist.

25. Housesitter.

It’s not exactly a way to make consistent great money, but housesitting—exactly what it sounds like—is a fantastic way to live in exotic locales around the world without paying a dime in rent. Did I mention it’s a way to travel and live rent free? Here’s a list of four great websites from the legendary Nomadic Matt, to start your housesitting search.

26. Babysitter.

No, babysitting isn’t just for teenagers and college students. Quite on the contrary, if you call yourself an Au Pair instead, you can make some pretty good side money working nights and weekends.

27. Property Manager.

Know someone who rents out property to others? Perhaps they could use a hand managing their property. If so, you can make a decent amount of money on the side with relatively little work on your part. From collecting rental checks, to managing repairs and improvements, or simply being on call for emergencies, a property manager is essential for most real estate investors.

28. Sell on Etsy.

Have a talent for crafting or creating other handmade goods? From bracelets to phone cases, rings, furniture, and more, Etsy is one of the world's largest independent marketplaces that’s perfect for anyone who is creative and willing to sell their handmade creations. As long as you have the space, this can make for one of the best home business ideas that can be started with a very limited investment. Consider these 5 steps to starting an Etsy store, from Handmadeology. Then, after you're able to build your brand and grow your own audience, you can start an eCommerce site of your own and retain a larger portion of the revenue from your product sales.

29. Ebay Sales.

Similar to selling on Amazon, eBay is a place to make money selling just about anything you can think of, with the added excitement of using the auction selling model to sometimes get way more than you expected for that antique baseball card you picked up at a local street fair.

30. Fiverr Gigs.

Fiverr is a great place for first-time freelancers who might not have tons of experience and want to build up a portfolio of their work. You'll be able to complete simple tasks ranging from logo design, to creating animations, or even drawing a company logo on your forehead.
