I think 50 to 60 is pretty fair but not competitive. Your equipment is worth something. What would it cost this guy to rent it and let his employee do the work?
You charge for equipment and man hours but maybe not show it that way.
More guys on the truck lower the cost of the truck and equipment and lower the effective man hour charges.
If people are getting down to $20.00 a man hour they are fools and likely cheats too.
