Photo sharing website needed

You are bidding on the design/build of a fully functional photo sharing website. Similar sites for reference would be [login to view URL], www.snapfish.com. This site will need to do the following: Register new users, upload photos into galleries, customize galleries, share galleries via email invite, print pictures, basic editing before printing, order prints. I have a 3rd party who will handle the backend ordering and I have the XML integration files that will need to be set up. In short, we need a site that does what the popular photo sharing sites are able to do. -
