Don't know what kind of income you're looking to get but I easily bring in $500-$600 /month doing eBay sales and I could increase that greatly by just adding more time to it (was doing over $1000/month when I had more time). If you do this you kind of need a niche type item in my opinion unless you want a bunch of competition which just drives profit down. I started out doing small engine parts i.e. I'd pass an old lawnmower, weed eater, blower, boat motor, etc sitting on the side of the road and pick it up. I strip the handles off, gas tank, deck, recoil starter, wheels, etc. You need to know about a little about the items you choose to sell and how eBay works. Make some pictures, add the item and wait till it sells. The more items you list the more eBay pushes you toward the top of the list of searches. Whatever items you choose to sell try to be unique, choose something you know about and are interested in and learn as much as you can about them i.e. John Deere items, Harley items, old concert tshirts, (those sell like crazy now for big $$) cast iron cookware, etc etc etc. You won't believe what things like old Levi's bring in from international countries especially Japan. Good luck.........
