Take good pictures. Some of the options below don’t require you to actually take the picture and sell the product, but for the ones that do, make sure you take a clear picture that makes your product stand out from the others.  If you’re going to be taking a lot of pictures, set up a small “studio-like” area in your home with a backdrop and proper lighting to really make your pictures come across as professional. And of course, you’ll want a good camera too.

(Even Bloomberg and Forbes feature stories from entrepreneurs who've done just that.) Services like TeeSpring make it easier than ever to create a t-shirt drop-shipping business where they handle the sales, printing, and shipping, and you’re only responsible for design and marketing. Or you can even buy into well-established franchise businesses like Rhea Lana that sell fashionable, affordable kids clothing and get the backing of a proven organization to fuel your online sales.

5. Fiverr – Fiverr is a great place to make a few bucks or spend a few bucks if you need some of the services people offer. Basically, everything is $5. You either pay $5 or charge $5.

If you’re a graphic designer and you want to offer your services for $10/hour, simply offer a 30 minute gig. If they need two hours of graphic design, they pay you $20, or $10/hour by buying four gigs.

Sure, there are some options like blogging that can make you a full time living but it takes a lot of hard work and dedication. But the majority of these methods, like surveys, reviewing, money making apps and so on, are not going to help you quite your day job. They are great for earning a little side cash in your free time. There is no need for me to hype things up and tell you otherwise.
