Ive been playing around with orderpicture.com
Their options for printing is almost too much. You can choose packages, singles and much more. The customer has the ability to add borders crop or what ever. You can either have the prints sent to you or the customer. They give you a base price and you can markup to your price. They give you a handfull of skins to use with your site. Thats one thing I dont like about it. There isnt a whole lot of room when it comes to buidling your site, not that I've seen anyways.
Heres my test site over there
Petry's Photography I only have a VERY small amount of print options and the prices have not been thought through so ignore those if you will. Check out
