I've benn told by one project manager that is common for an insurance company to pay $300 for disconnecting some lights in a flooded basement ...sometimes less than one hour of work.
If you are in the service business, you will soon descover $300 fo an hours work is not a lot of money, as a matter of fact it is more like the min rate for service work, once you add in your non productive time, that $300 is long gone.
