PSA, Assignment, flex contracts for wholesaling. CA

[Brian Chanax]

hey guy ! I'm just starting off as a real estate wholesaler and I was wondering if any one knows where I can get simple PSA, assignment addendum's, and flex contracts ? I say simple for the PSA. I find that home owners are more opened to do business when they see a contract that is not very complex. If anyone can help I'd be very grateful !
