I just today opened a website called http://beArtful.com, which I've been working on for a while.
I guess the concept is pretty easy Just upload a digital image and we can make a print of it, either for you the artist (wholesale) or for anyone that finds your art on our website (retail, you choose the markup and whether or not it is available retail).
You also get a free subdomain (http://user.beartful.com) so you can direct people JUST to your art if you'd like. The prices are great because the website is owned by a large giclee printer that has been in business for 20 years now. Basically, the prices are as close to wholesale as you will find online without minimums.
Anyway, the site is
and new and I'm sure there are still problems with it But check it out!
