I don't think such a service exists. I think I found one legitimate one which cost $40 per dupe or something like that for which cost I purchased some 4x5 Fujidupe film (now discontinued, check ebay or use the Kodak Equivalent) for cheap and contact printed them with the dichro enlarger. On the 4th 40 minute process length control strip I decided maybe I'd just project the originals. It can be done and is probably easier once calibrated, but it's a pain.
