IMO…Trying to find a kit would be tough to do. I bought everything I wanted, and it was not cheap. But when I did it, I did it with the idea I'm buying once. Not buying cheap with plans of upgrading.
I think I'd maybe think about having the class and letting everyone make their own choices about their gear.
I thought about having a free firearms safety and familiarity class for family, friends, and neighbors. A non-shooting safety class coupled with letting them handle various firearms and answering questions by someone that's not a salesman. I haven't pursued it for a few reasons, the biggest being questions of liability. I'm sure if I asked an attorney if I could be liable if someone, I trained that got hurt later, they would tell me yes. It's the times we live in.
We see too many people hurt handling firearms, and too many people hurt, and guns blown up by reloaders. That shouldn't happen if a person is properly trained.
It's a good idea. Good luck.
