Steven, my friend uses
www.VanGoghAgain.com for his giclees and he's very pleased with them. They're in Drexel Hill, Pa., just outside of Philadelphia and he brings them the original for scanning on their huge, state-of-the-art flatbed scanner. I note from their website that they can work from other sources if the original isn't available.
HTH! (which means "Hope this helps!" by the way)
