I find that quality of workmanship, and the end result very variable. It is very difficult to find true, dedicated professionals these days, those few I do find, I put on speed dial.
I needed some rust prevention work done, on my car, found a local company who claimed they could do it. The end job was where they did the obvious visible bits, and left the bits that involved any effort. I asked for the four end/ wheel corners of my brakes to be renewed, they only did the two easy ones. They had my car, several days longer than they quoted. When I inspected the work, and saw what little they had bothered to do, I went back and complained, they then had a second go, during which they managed to drop the car on a toolbox or similar, and scrap the underside. This, whilst extolling the virtues, and cost, of their rust preventative chemical. The rust is already poking through again, so I'm thinking to tackle it myself. It was only a matter of rust-proofing the rear arms, the rest of the car is/was well rust proofed at the factory.
I needed a small hole in the outer skin of my back box welded up, I rang a local company to ask if they could do it, and had a long friendly chat with the owner. He said it would not be doable, because it wouldn't last/ be too brittle, but referred me to another company instead, who could custom-make me a new box. I respect that guy.
Rather than risk a much worse job, and being ripped off, I tend to do most of my own work.
