If you live near a university, there are likely all sorts of research studies looking for participants. While I was an undergrad at Virginia Tech, I got paid $500 to participate in a 6-week dietary study. The study provided all my meals and paid me, but I had to eat a 5,000 calorie diet of 50% fat for 6 weeks…plus I had multiple muscle biopsies, urine, and blood testing.

21. Facebook – Facebook swap shops are great for selling things locally. It’s like CraigsList, but a little easier. You simply search for swap shops in your area and ask to join the group. Once you’re in, take a picture of the item, write a quick description with the price and post it. It doesn’t get much easier than that. You can generally expect to get about what you would get at a yard sale, maybe a little more.
Are you an animal lover at heart? How about making some extra money just by taking a dog for a walk or boarding a cat for the weekend? You can advertise your own pet-sitting business on social media, put up signs throughout your neighborhood, or use a website like Rover. They let you set your schedule and adjust your fees as you see fit. If you do use Rover, keep in mind that they take a cut of what you make.3
