Joint venture advice

[William Johnson]

I have an owner of a distressed property who has almost 160000 in equity in her property and the best usage for the property would be to convert it to a triplex. Her husband and her are too burned out to manage the large project so I proposed that they pay for the construction and I manage the entire project for them. 

What do you think would be a standard, fair agreement to offer them? I was thinking that 10k held in escrow until the construction project is completed whereupon it would be released to me.
