Don\'t give up. My photo lab that I use for my event photography software (the lab is the backend print shop for many of the major photo sites in the US) has a great color matching process. These are the photo prints you would get if you uploaded a photo to a website for printing or if you were at Little Johnny\'s baseball game and the pro photographer took his pic while he made the game winning hit.
I can do many formats, including prints for wallets, 4x6, 5x7, 8x10, 11x14, 16x20, 30x40 and other items including mouse pads, photo key tags, picture mugs, photo magnets, luggage tags, 4x8 greeting cards, etc.
Not sure what price you are looking at for your custom shop you are using, but I get wholesale rates because I send dozens of customers through to the lab in bulk via an automated process. I never have to touch the photos...my server handles everything.
