The kind of investigation to be conducted (which, for example, can be based on the level of a security clearance needed) will depend on the reason for the investigation. Different kinds of background investigations have different requirements for the scope of the investigative coverage to be obtained.
Instead of trying to measure every inch of masking tape used and every ounce of paint sprayed, auto-body shops charge a flat rate for materials. At a rate of $45 per hour on average, paint materials also contribute to the rising car bumper repair costs.
Okay, back to the $35 per hour average. I think it is important to point out that you get what you pay for. Right now, the better bookkeepers that I have sub-contracted with from time to time are actually charging $50 per hour. quick look at Craigslist will show a million bookkeepers with rates from $25 per hour to $50 per hour. In my mind, I think $35 per hour is average. But there are a lot of factors here.
