Apologies, I. don't have quite the answer your looking for, just some advice.
I completed a CRI as my first instructor certificate and it did open doors. But the training is in my opinion dangerously short. I understand the intention was to basically create a TRI equivalent for DHC-6, C208 and SEP MEP Class without becoming a full FI(A). But just as in the case of a TRI you do not get taught how to teach people to fly only how to convert to class / type. If you try to correct fundamental flying techniques without knowing the approved theory it can go badly wrong.
The FI(A) course is long for a reason and it annoys me when I come across Airline training departments that look down on FI(A)s. Sorry rant over.
I agree you should be able to be paid as a CRI with just a PPL.
Best reference I can find is in the UK ANO
