If I were in your position I'd find out what the local ranges are charging hour for hour for their classes. Then I'd knock a little money off that at first, maybe $10 to be competitive and raise the price to be equal to theirs after I had a few classes under my belt.
Then to drum up interest I'd make up some fliers that describe the class and advertise that FIRST TIME ONLY the first X number of people to call and register get in for free (small sample size of the crowd you're going for) and print up fliers for all the ranges to post on the boards.
I'd also print up some coupons with a slight discount to give to the people I talked to face to face.
