Front end rebuild - what's it worth?

A friend of mine has a small vehicle repair shop. A customer who regularly has him work on his modern vehicles from out of town bought a 66 Dart and has been bugging my friend to do some work on it. My friend told him he doesn't usually work on classics as thy are usually not financially feasible and asked him if he could find anyone else to do the work. The guy has not been able to find anyone within a reasonable distance that will work on his car so my friend agreed to do some minor engine work for him. The guy also needs the front end rebuilt and my friend really doesn't want to tackle that. He asked me if I could help both of them out and rebuild it for them. It needs upper control arm bushings, lower control arm bushings, strut rod bushings, upper and lower ball joints and tie rod ends. The pitman arm and idler arm were supposedly replaced a couple of years ago so it doesn't need those. I've got plenty of work to do on my own stuff and my local friends utilize my free services whenever I have time. So, my question is, what would be a fair price for a front end rebuild on an early A? Looking for a rough idea that would be fair for me and the car owner. I'd like to do it for him for free (just because he's an early A guy) but he needs it squeezed into a certain timeframe so I figure it would be fair to get compensated for my time, and my buddy would like to give him an estimated price. If I charge actual cost of parts what would the labor part of a job like that be worth?
