Wholesale Contracts PLEASE HELP!

[Alan Mohabir]

Hey, I am starting out Wholesaling and I have a deal underway with an assignment fee of $91,000. Noting the profit I am going to make I wanted to undergo a Double Closing. I was wondering about 2 things. The first being are there any assignment contracts someone can send me that states my assignment fee within the Sale Price, and the second question was, are there a different set of contracts for double closing, as opposed to a regular closing. 

Here is my exact deal. 

I got a home under contract for 200k, and I found a buyer that will pay 291k. What contract can I use that hides my fee, or what can I do to hide my fee. 

PLEASE ANSWER IN DETAIL...I AM VERY CONFUSED and this my biggest deal yet and I dont want to mess it up AT ALL!! PLEASE HELP
