How to create a deal with a contractor?

[Fasil Khan]

I recently met a contractor that is interested in investing in real estate, but does not have the cash to put in, however, he can offer his services so I was curious to ask some bigger pocket members, what is the best was to brokerage a flip with a contractor if anyone has experience or suggestions? What % would you go for at his end to make a win/win and long term relationship?
