I am curious what the average rate per hour is, across the country, by state or region, for a service truck/electrician to go to a home and do a repair or similar work.

I know that the company I worked for previously that was largely service work oriented, billed $55/hour for a van and 1 man, plus materials. $85 if it was an emergency/night.

Is their any kind of a database anyone knows of where I could locate this kind of info?
