City,
Remember also that class size matters. Each kid has a potential weapon in her/his hands and your liability insurance is probably next to non-existant.
You are going to need a couple paras that buy into what you are doing to help you with supervision and on key message.
I merely suggest you start small and let it spread, but not too fast. Maybe you could start with training a couple volunteers this summer on the golf course and on the range. Maybe one will be an administrator, a teacher or two and a para or two if they are available. Maybe a young assistant pro in the area has a little interest in doing something for the benefit of others (good luck with that).
