This sounds like a job for a pro. I wonder if Ceri remembers when we talked about this before, and how I had to do this operation on my old Ibanez. I posted pictures of how to deal with it and people still misunderstood the process.

Really I would be leery of any shop that doesn't know how to fix this issue. There is absolutely no advanced woodworking involved. What it takes is a lot of care and diligence. And most importantly patience.

Issues like this creep up because the vast majority of people don't understand the function of the truss rod. I would bet the problems with your neck were created by someone with no knowledge and no patience monkeying around with the truss adjustment.

like i said before, dan covers this in his book. it didnt sound like a hard fix at all actually.

you are right about avoiding stores with limited repair experience
