@erikdiamond - Not a problem!
Some people include it as part of the proposals, others leave it until later when they really dig into the project details. The important thing is to have them sign something at the proposal stage, even if you're not going to give them the detailed contract at that point.
I'll send you a PM and send you a copy of a contract so you can see how that differs. I'm somewhat hesitant to make one available for download as it's always recommended that you hire someone to draft one up for you. Every business is unique and every project differs. Not only that, but laws differ by state as well. Just something to keep in mind.
