How do you find GREAT wholesalers?

[David Schach]

I posted yesterday about a bad wholesaler that I came across on BP a few years back, sorta turned me off to the basic concept. But now I have some cash sitting on the sidelines and am actively looking at deals now. Where are the great wholesalers at? not just the newbies that have NO clue what they are doing but seasoned vets who know the game and understand how costs break down. 

As a side note, what do flippers usually like to make over the wholesalers? The wholesalers did the leg work, etc. But the flippers take 100% of the risk. In my opinion I would like to be making close to 10 times what the wholesaler made on the deal. Does that seem too rich?
