You can sell your ebooks through Amazon's Kindle program or Apple's iTunes Connect, which gives you access to a large majority of the digital-book reading market and the barriers for entry are incredibly low.

Research Pricing (And Set Fair Starting Prices): Before setting prices for each item, research your local Craigslist website and (if possible) nearby yard sales to get a sense of how to price them. Remember that many buyers will try to haggle – so set prices a bit higher than your bottom dollar, but not so high that you’ll scare off first bids. 10% to 15% is a good rule of thumb. Consider bunching low-value items, such as old CDs, into lots of five or 10, or offer x-for-$y deals.
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.
Persistence and Commitment. You’ll need to have a good amount of persistence while pursuing freelance writing gigs. This business is subjective, and while one person may love your writing, another may not.

Just by committing to do those two things, you’ll be miles ahead of your competition.

Nielsen (the same company that creates TV show ratings) has a research division that is similar to what survey companies do, which is gather information to help companies better market themselves to customers. Instead of having you take surveys, though, their computer and mobile panel is focused on gathering information pertaining to your “unique internet usage with people like you to build a picture of internet behavior.”
