Mufler brackets on 2004 Ford Explorer

My car needs to replace 3 muffler brackets. What should I expect the cost to be?

Shouldn't be more than an hour or two of labor plus brackets, have your local muffle shop give you a estimate
Your answer "Ask your local muffler dealter" doesn't help me because I am trying to decide if the estimate he gave me is good or bad. What do mechanics charge per hour? How much is a bracket? Those are the kinds of answers I needed to know.
