I have not personally had work done by Carl, but he has been a contributor over @ Team Chevelle for a few years now and his shop appears to be very capable of the work that you are looking for. It have talked to Carl about a few jobs, I just haven't needed his services yet. I will be sending my next project to him.
Good Luck.
