Seeking a Win - Win Contract

[Joseph F.]

I am plan to rehab a property. I will purchase the property and finance all of the labor and materials. I have spoken with a contractor, but have never used him before. I will make sure to vet him before I agree to enter into a relationship with him. However, even then there is always a risk. I would like to keep him on schedule and committed. Does anyone have a good win - win contract? I would like to offer incentives on staying on schedule and coming in on or better yet, under budget.
