Go to mike holt's site, under free stuff he has a good start for a proposal. You will need to modify it to suit both you and your state laws. A "good Agreement" is one that leave no doubt about what is to be done when and how you will be paid. Good luck

Used this as a base for my current (pun intended) contract.
Added a check box indicating whether it's an inclusive bid, or a T&M job, added a "Location of work" line & added a section under "Owner/Contractor defaults" for NSF / closed account checks. I also dropped the "Terms & Conditions" section down to a 9pt font, and was able to fit it onto a single page with .5" margins (saves paper)
