I am about to buy my first rehab and I need to find a contract that I can put in place between my partner and I and the contractor. This will be a time and material job if that makes any difference. Where can I find a decent contract? We will do some of the work ourselves(demo and electrical). Any suggestions would be appreciated. 

Also, is there other documents we should have for our protection. I will be paying all cash for the property and rehab. I would like to get this thing underway but don't want to jump in and get blindsided by anything. I appreciate any suggestions.
