There is a reason that most of won't take on trainees and that is because after 2-3 years the trainee gets certified and wants to find clients of their own and not return to the person who trained them. How about signing up your mentor for new clients for a couple years and build the business and get a higher fee split?
The reason we don't hire trainees is because we don't want to compete with the people we trained after three years.
I think you're misunderstanding what I'm saying and asking. I'm not trying to go off on my own with my own clients. Like I said above, I'm still working for him, but we are trying to get me set up so he doesn't have to join me on inspections like he did when I was a trainee. This has to be possible right? Even if they are assigned to him initially and he can pass it on to me, so all he has to do is review/sign. Even better is if I have my own approved profile, orders are assigned to me and he doesn't need to review/sign because it saves us both time. Either way they still pay his company, not me. I'll sign him up for every client in the world if it means I can get more orders myself without his direct supervision, that's all both of us want. Fee split is not a concern, I have a very good deal as it is a family situation. I just want more volume to make more money, not a 100% fee with no split.
Firms have more than one person and they are able to get orders for multiple people working there, that's all we want. He just hasn't had someone work for him in a very long time - probably since before 2007 (probably for the some of the reasons you mention about trainees, but again I'm in a different situation).
Really this all stems from the one client I specifically talked about above because they are by far our most active at the moment. They approve trainees, who get their own profile, but are only assigned jobs through their supervisor's profile. The trainee is then allowed to inspect alone (obviously if competent), with the supervisor obviously signing the right side. However, when I inquired about me as newly certified they said they require 2 years of certification. It can't be right that I'd be better off as a trainee with this client than I am now, can it? That just doesn't make any sense. We're fine with him still reviewing and signing if that needs to be done. We've tried to be clear about what we're asking several times, but maybe they are misunderstanding as well?
Again, not going on my own. Just trying to get more work through him.
