I don't mean to knock you, cavo; but a manhour is a manhour. Whether it's for one man or two or more. Besides, the term manhour is pretty much a given for everyone to understand. And, your customer really has no need of knowing how many manhours you have in your bid or quote. All their interested in is if its a Service Call Rate. Don't let your bid quote rates be known.
Though it varies in different regions and as to what type of construction you are doing...manhour rates can vary from $15.00 an hour up to $65.00 an hour. Normal commercial quotes vary from $18.00 to 25.00 per manhour; while Service quotes vary from $55.00 to $65.00 an hour per man with a 1 or 2 hour minimum. Some apply a trip charge for the first hour. Varies from $25.00 to $45.00 trip charge for the first hour including rates of the Men applied.
What you need to do is figure and calculate your actual cost up front including your overhead and develope your standard rates for quotations and service.
