If you are still looking for a qualified shop in the SoCal area, I highly recommend Scott Melnick at Auto Engineering and Classic Mercedes Benz in Calabasas. I have had my 68 280sl in Scott's shop twice . . . from Spokane, Washington! Scott has years of experience working on nothing but classic MB's. There is no aspect of repair/restoration that he can't handle. The first time I drove into his shop (located in Malibu at the time) I pulled in next to a 300sl Gullwing, and a Cabriolet undergoing a complete restoration, along with three or four 113's. Call Scott at 818-222-1800.
