Gentlemen:
FWIW, for 'small' jobs I used a 'Proposal' form that was self generated. Names, jobsite, and description of work. Explanation of Insurance/WC, and the terms of payment. Spelled out the terms for any additional work that was requested, and that it MUST be in writing, signed by a 'responsible person' with the additional costs. Explained permit and inspection responsibilities, and that final payment is NOT payable until final inspection and approval. (That is NJ State Law)
For other jobs, I used the AIA contract format, which was drawn up by the architect of record.
T&M work was performed under a written contract which stated labor rates, travel (if app), and materials MU%. The usual legal items, and that was that.
The above worked for 25+ years, and there were quite a few 'handshake' deals that also were non-eventful.
Unfortunatley, todays climate requires more 'input' from the legal scholars for any contractor to stay out of trouble.
