Advice structuring a partnership

[Michael Alan Graff]

I've got two houses that need rehab, both with good equity potential once finished.

What kind of deal can I propose to a potential builder to partially pay them in equity. I'm thinking of paying them once the property sells or rents. That way, they not only get paid for their work, but how well the final house sells or rents.

I was thinking of a weekly pay stipend plus a bonus at project end. 

To add complexity, I was thinking of helping out., And they may be able to land grants, get inexpensive help from classmates and other value added activities.

I've got a potential person in mind who just got out of tech school for building houses.

Any ideas on what to present as a partnership? Not sure 50-50 is fair to me if I'm finding the house, paying a stipend, paying for labeor and buying supplies.
