It is unfortunate that your only exposure to an NRA certified instructor led course was for your state Concealed Carry license certification. Often the state certification course(if there is one) is not up to the standards of an NRA certified course, but designed to be a Quick and dirty basic training and sanity/safety check on folks getting a state issued license.
Most states that have such a course rely on NRA certified instructors to teach those courses.
I know that the real NRA courses can be difficult to locate and costly to attend. I took my basic courses at a local gun club. I then had to travel 3 hours to a Boy Scout camp and stay overnight two weekends Friday morning to Sunday morning to complete all my instructor courses. The cost was about $600 for the basic instructor basic pistol instructor, basic Shotgun instructor and range safety officer (self study), food and lodging (4 nights) at the camp.
I was 48 years old at the time I took the certification courses. I had been an avid shooter since age 11 who took many first time shooters to my club and taught them basic safety and to shoot, rifles pistols and shotguns.
I found the NRA basic instructor course very very useful. In fact the basic instructor course will help you think about training people in your regular job differently. They will help you develop the Knowledge, Skills, and Attitude to properly train others in the safe use of firearms.
So I would advise you to check the NRA website for training in your area, You may also want to contact the Boy Scouts of America. The Boy Scouts only allow NRA certified instructors to run the ranges and the merit badge programs at their camps.
Many times the BSA chief range officer at a camp will be an NRA training counselor and will run basic courses for folks who are interested, in the hope that they will volunteer to help out at the camp in the summer months.
The cost of these BSA sponsored courses will be less than at a privately run club and the instructors have a great deal of experience training new shooters. You may also decide to help out with the camp range in the summer, its a great way to gain experience teaching (shotgun and rifle).
