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.
This markup will vary depending on the type of shop it is, and the job, but an average markup for parts by a mechanic is between 25% to 50%. This means that a part that a mechanic pays $100 for will cost you between $125 and $150 on your bill from the mechanic. Don't forget, this is in addition to the labor charges, which average between $85 to $110 an hour for independent repair shops and between $115 to $135 for dealerships.
