Maybe someone else will have a better suggestion but I don't know anywhere in Jacks that I would trust with this level/type of refit work on a good boat. Suggest St. Augustine on the San Sebstian Creek and the Oasis boatworks as your bet bet. They are capable of all you need done and we had a friend on a big Hunter who did a similar heavy refit and was quite pleased with their work.
Oasis Boatyard and Marina
Good luck...nice boat!!
Just as an aside...you may want to review these threads on Richard Kollmans (marine refrigeration guru) forum before settling on this as the right way to go.

A quote from him: "I believe Frigoboat has a design and quality control problems with their keel cooler
and compressor system. It should not be necessary to replace evaporator assemblies because capillary tube is blocked or a keel cooler
because of a leak.
