Nikon F4 Repair Rec's?

I recently bought an F4 that is pretty clean externally. However, when you fire the shutter, neither the mirror or the shutter moves. The little red light on the left side of the camera starts blinking repeatedly until you do a power cycle. The seller gave me a refund and said to keep the camera so, I guess I'll try to repair it. KEH said they would take it, but I thought I'd ask about other options just in case someone can recommend a shop that will do a good job salvaging an otherwise very nice F4.

This one is w/o the vertical grip which is both more rare and my preference. l've wanted an AF camera that will use my small collection of AFD and Voigtlander lenses, and also matrix meter Ektachrome.

I used Camera service pro for a Nikon f5 with shutter issues. Great service. Would used again

APS in Illinois would be my suggestion since they used to be the the NPS Central depot back when the F4 was new and being worked on, they've done some nice work over the years on pro level Nikon
