Cost is dependent on where you take it. I was doing front clips for $1000 labor . No body straightening , No Paint, No parts. Prepping clip is extra time . Tow it in on an Friday and drive it out on a Monday. Three guys three days.
Now its only 2 old guys. We are much slower then before my son moved to his new shop. . But we made it much easier though with a 108 wheel base fixture. Crane , Fork lift, and two post lift does all the heavy work. Its only a 4 car garage but its organized since the machine shop is moved
Find someone near you that does these cars. A normal body shop cannot do it cheap because they are not set up for a single model/WB car . Measuring for fitment takes more time. With a fixture made for your car? It is set it on, Tie it down and weld,
