Need help with writing a contract with a buyer before introducing him to a seller?

[Fredy F.]

cliff notes:

-A good friend of mine :) who is a real estate agent has a deal that I forwarded to one of my buyers on my buyer list.
-Buyer from buyer list really likes the numbers and wants the deal.
-I negotiated my referral fee with my good friend who is going to make a contract for the two of us.

My question is what kind of contract would I use for my buyer? I want to negotiate a consulting fee with him, before I introduce the two of them to talk about this deal.

Thanks!!!!
