lawyer/legal aid....
Id add that you might want to speak to your business lawyer(legal advisor) if you have one or do some research on the state laws/statues re: weapons training, tactics.
My state has a few gun/weapon statues that say you can
not teach "militia" type instruction or form/create any schools, education material etc intended for weapons training, tactics, skills related to military forces.
If you have a state certification or license that may help you clarify what your course(s) are. A NRA certificate may help too,
.
It may seem minor or trivial but Id still look into it so a DA or media source can't make a issue of it later.
The scandal with TN's James Yeager of Tactical Response is a good example.
