What percentage of the GP stake should the lead finder earn?

[Keith Miller]

My partner and I are about to set up a 506(c) syndication for developing industrial condos, and we are in discussions with a potential partner who would focus on finding leads for land. If he starts making cold calls and eventually brings a lead in that we buy, what percentage of the GP stake should he earn? Has anyone here given the lead-finder a percentage stake of the GP before? Any insight or experience would be greatly appreciated.

I have set up several GP partner allocations here is how I have seen the five groups break down. 

Deal Finder 10 - 15%
Risk Capital 10 - 15%
Loan Guarantor 10 - 15%
Asset Management 30 - 35%

Investor relations 30 - 35%
