Just a thought, if hes your buddy, then do what I do.
Do the job for free, just get him to help you with the little stuff, and bring the food and beverages. Take tons of B&A pics, have him give you props on any social networking sites hes on, take some of your cards etc.
I have done 4 or so vehicles like this, in fact both of my cousins have recently acquired new vehicles, well one new, one beat to death but I will do both for an EXTREME discount if not free just to get my name and skills into their circles.
Just how I spread my name..
