Contracts for Sub Contractors to Sign

[Chris Summons]

Hello BP Community,

Well I am official, I purchased my first house to flip two days ago.  Yay!!!  As I start to look at what sub-contractors I want to use I wanted to see if anyone has a good base template for sub contractors to sign? I really want to have them sign a contract that I can drop in the scope, schedule and proposed fees to provide some protection for me. Anyone have a good base that they are willing to share?  

Thank you so much for your help!!!
