Depends on what you are doing with the car, they do it all, you do some work/strip it down. What about the running gear and engine?
If they do everything for you it wont be cheap you may be better off buying one that someone else and already done unless you are attached to these cars.
A bit more info and some pictures may give us an idea on what you are going to be, the hardest thing is in pictures they can look good but it's the hidden stuff you have to watch out for, you start stripping back things to find more problems.
