Recommendation on Mechanic

Gentlemen: I am in search of a Corvette C4 mechanic in the Orange County CA area. Currently I need the power booster replaced, but I also need the driver's door aligned and window stops replaced, in addition to having the modification done on the inside door panel to bring it back flush. I've tried the local Chevy dealers, but I'm sure most of you know what kind of service that gets.
Any suggestions?
thanks
