FWIW NAUI has something called a "Training Assistant" that you don't hear a whole lot about. What you are allowed to do is very similar to a Dive Master but without the insurance requirement. I've never seen one but when I read about them in the "Standards and Policies Manual" the way a Training Assistant is described made me think "that's a dive master with no professional liability." Might be worth researching.
