contractor partner investor profit vs. investment options

[Dan Chapman]

HI, My main partner is a general contractor we have 3 of us total investing in fix n flips. Two of us help find the property and I set up the loan or financing. My question is are there any good sources for factoring how profits are shared with our contractor who is doing most of the work with the fix n flip? Meaning if he does not put in any money what percentage of the profit would they normally get for doing the rehab work? Versus if they invested a smaller percentage? I have seen one that shows the contractor getting 50% of the profit with no money in the project just labor.

Thanks, Dan
