Firearms Safety/Instruction for Teenagers

I am looking for some firearm training/safety instruction for the 16-18 year old young men of my LDS ward.

Requirements are thus:

1. Something that would last no longer than 1.5 hours on a Wednesday...likley late afternoon/early evening.
2. CHEAP.
3. NRA or Utah State certified instruction.
4. No travel outside the SL Valley, unless it is to the uninhabited, 'shootable' portions west of Utah Lake.

Shoot me a PM or email if you are willing or able. Thanks!
