Wholesaling with a Quit Claim Deed

[Maria Gomez]

I'm working on a wholesale deal in which I and the end buyer will be listed on the contract of sale. After the closing, the end buyer will pay my wholesale fee and I will quit claim the deed. I've been looking for an agreement that secures my wholesale fee with the end buyer and ensures the end buyer I will indeed transfer or sell my interest to him. All I've been able to find online are assignment contracts. Anybody have any leads on this?
