MTT Coach ?

[czGLoRy]

SO, I am interested in getting a good coach for MTTs. The thing is, I don't think paying an hourly rate is very sensible for coaching.

I would prefer to do something like split my wins 50/50 with the coach, over an agreed upon amount of buyins/games or time . Splitting the wins would encourage the coach to take a more "proactive" responsive, as well as any student.

Is there anywhere something like this is done?
