Hi Matty,
I've known Craig for 10 + years from where he is now in Livermore and his old shop in Pleasanton. Craig was an SPF dealer and built a lot of cars for many people here in the Bay Area. He does good work but, can be expensive. I would recommend regular stops to review progress and be explicit as to what you want done and getting a firm idea of the cost up front. When left to his own Craig will go to the extreme detail and $$$$$ which may come as a surprise when you are presented with the invoices for the work.
I'm sure some of the people that know him will also contribute additional information and opinions. I have done a lot of business with Criag but, there are other high quailty service providers that are more reasonable for their services.
You may want to drop into the Rock House for BACC breakfast any Saturday morning and talk to the group. There are many of the cars that Criag has built that drop in most Saturdays.
Here is a link to the BACC website for directions etc. :
