i wouldn't go with ebay at all. the terms, price, risk and competition makes it a poor option for most people. zazzle and the like may have some ownership issues you're not too hep on, not sure, but it's something to check out. some sites allow you to create free or very cheap pages to sell on (i want to say etsy, bigcartel and a few whose names are on the tip of my tongue that i can't think of, so i hope someone will help me out here).
do the social media sites, like facebook, twitter, etc.. i really don't see many honest reviews on those places, though, but it's almost a requirement these daze that you have that presence there.
hard to say what's the best way to test your market. you're probably realizing now that you should have done this as part of your market research, huh? lol. but, since you didn't, and most people don't much to their chagrin later on, it's impossible to say without knowing who your market is and what it is that you make. it's a safe bet that you need an online presence, meaning a web site, and perhaps some SEO.
it sounds as if you're rather ill-prepared and under-funded, making the design part a reality without much consideration to the real work of having a viable business. it's something i've seen here literally a hundred times. so, how far are you willing to go with your business? are you at least willing to put the money into it? great designs won't get you very far without letting your prospective market know you exist, and that more often than not takes money, and therein people fail with their dream having spent more time fantasizing about being the next johnny cupcake or affliction and the 'ease' at which they've achieved success than hunkering down and establishing realistic goals.
fat-k, i like what you do. 'no order to small' should read 'no order toO small.' on the page that describes your process, i found the text hard to read once the orange began to fade into the darker shade toward the bottom. just my un-asked-for opinion.
