Seeking Recommendations: Repair for Retina Reflex and Zeiss Contaflex III (in U.S)

Does anyone know of a repair tech located in the U.S. who will still do general service on either of these models? I had mine ready to go off to Essex Camera Repair in New Jersey, but they now appear to no longer be in business. Before considering the extra cost involved to send to international destinations, I thought I’d ask for other options you might know of. Thanks!
