I'm redesigning my site to include an option to purchase large prints of my work. Does anyone know a good website that I can link people to from my site to be able to purchase these? I'm looking for something where I can set the markup for each print and where I don't have to do anything other than upload the print file, and then let the company take care of the orders. It would also be cool if they would offer different sizes. So let's say someone wants to purchase a specific print, I want them to be able to click the link for the print, and that link direct them to the ordering site. Any ideas?
