Hi hika.
How about trying thhis place
http://www.cafepress.com/You make an account there, upload some designs and set up a shop.
There are other things you can create and sell there such as mouse pads, mugs, steins, t-shirts, hats and caps, clocks, kids clothing, mens boxers, ladies thongs
I helped RTCW wildwest create a shop there. Take a look
http://www.cafepress.com/TheWildWest (I bought a wildwest stein i designed, pretty cool actually)
It's easy and simple and free to set up.
You choose the products, place your designs on them, they are already priced, you just up the price a little to make a profit. If profit is made then put it back in to this game.
If you do create a shop there and need any help, just let me know.
It's worth taking a look.
