I am a NRA Training Counselor (trains NRA Instructors) so I understand your quest to find a reputable instructor there are some scary ones out there. Since I have met quite a few I can see the good from the bad and I know of one in the FT.hood area that is reasonable.
I also teach CHL but you are pretty far from me as I live in San Antonio. His name is Duke Johnson and he teaches police, CHL and I certified him as an NRA Instructor. You wont find a more reputable person for the price. Shoot me an email and I will send you his contact info.
