Just a data point for OP, I had GREAT experience with the roadside werx crew when I bought my Disco from Land Rover Denver.There's two good LR-specific shops in Denver, Roadside Werx and J.C. British. I might make an appointment to have one of them take a look.
As to the rest, if the guy just does stuff “on the side” and isn’t a true business, then I could see why he’s not directly involved. OP, forget the dealer. Go over to Roadside Werx and see if they can help.
