I am picturing a metal grommet that goes around the bundled wires where it passes through the framing that would act as a protector against nails.
Audiophiliac hit exactly on what we've had to do on walls where a smooth, flat finish was involved, protect the wires on the inside of the stud. We did that because moving the wires was going to be a pain.
However, if it's a flip house, just tell him to 'hire a pro' drywall company... might be a lot to ask though, haven't seen one of those in years.
