Audiomad, The best option for you would be to create your own website, display your artwork on it, then drive traffic to it so that you will build up a fan base and get a lot of sales. I'd still use a separate printing agency while you're starting out, because if you don't have a lot of money to sink into it it's much easier if someone else prints your designs. I'd recommend trying mysoti.com. You can sell shirt designs, artwork, and lampshade designs there and they seem to have a pretty active community. Good luck! -Benjamin M. Jacques
