Contractor contracts with a share in the profit

[Jennifer Handlin]

I flip homes and have been the GC on the projects, I would like to find a contractor/partner to share in the profit and in exchange manage most of the GC work, while foating his labor until the house sells and receiving a % of the profit. I will still be part of the project but not have to be on site everyday. Looking for a contract that provides both parties with expectations and legal verbage. Any experience/recomendation?

THANKS!
