Sites like Cookening, EatWith, and MealSharing are to restaurants what Airbnb is to hotels. Sign up as a host to earn dough by cooking and serving meals to guests in your home. It's up to you what you want to cook and how many people you can accommodate. Cooks are paid directly through the site, so no cash ever changes hands. The earning potential for becoming a cooking host is $50-$100 per meal.
Turn your photographs into cash via sites like Fine Art America, which lets you upload your images to sell as prints, t-shirts, phone cases and more. Other marketplaces for photographers include SmugMug, 500px and PhotoShelter. Some sites require a subscription but may provide features ranging from cloud storage to password-protected galleries and a customized website.
If you’re trained in a marketable skill — like graphic or web design, SEO writing, or video animation — to the point where you can bang out the work in your sleep, you can make a pretty quick buck with it on Fiverr. Whether it’s the best long-term strategy for your freelance career is debatable – and it’s one of the least lucrative gig economy side hustles out there – but that’s not the point; the point is that there’s the potential for earning money quickly.
My 10-year-old son brought home a book from our park’s free library box. It was a biology textbook – teachers edition. He said it looked interesting and hey, it was free (having no idea you could sell it). I scanned it in my Amazon seller app and realized it was worth around $150. He was so excited. We listed it for sale for $130 and it sold! Going to tell him, he just made $130!
If you don’t live in a bottle deposit state, you can still cash in on recyclables by selling scrap metal. You may not have enough soda or beer cans lying around to make this worthwhile — and steel prices are so low right now, it’s not really worth the bother to go collecting them. But if you do have a lot of aluminum cans on hand, or if you have any scrap metal with copper in it, find a local recycling center and see what you’ll get (prices vary wildly by market). Still, unless you have a lot of copper pipes lying around the garage, or bags and bags and bags of old soda cans, realistically, we’re probably talking about getting $5 to $20 back.
