Looking for a document to send to contractors

[Ben Gradert]

Hi, I am doing a value add to a 700 sqft home and adding a 1,000 sqft addition to the home. I will be hiring a lot of contractors so I was curious if anyone on here has a good template they've used that says: When work will start, scope of work, estimated completion date, cost, and signature at the end. Then the only other doc I am looking for would be for the contractor to sign to say work has been completed, payment received and they can't put a lien on my home.
