mentor searching protocol

[Meatmaw]

Does anyone have advice on how to best search for a mentor specifically for playing 1-table SNGs? Is there a faq around on good ways to look, or do people just ask people individually after determining they trust them etc? I'm interested in what kind of pricing models there are too. Naturally I'm inclined toward results-centric ones but how much do people typically charge? Something like 30% of profits over 400 sngs? Just curious what is usually done.
