If you're after a one stop experience, you could try Outer West Smash Repair and Resto on Coombes Drive, Penrith.
I have no experience with them at all and have not spoken to anyone that has had work done by them. I was fueling up my Z one afternoon and a sky blue, Datsun Sports/Fairlady pulled up on the forcourt, the guy hopped out and almost ran over to me. He introduced himself as Marcel Santini. Apparently he is the owner of OWSR and he seemed like a very keen Datsun fan. Unlike most smash repair folk, he seemed very keen to take on resto work.
I did ask him whether the work they did was good or shite. While he was taken aback by the question, he seemed genuine in the belief that his company produced a quality result for his customers. This is their facebook page:

As I said, I have no affiliation or experience with them. Maybe you can get some work done and then tell me what they're like.
