Don't have it but on my proposal letters I simply include a box for the purchasers signature, purchasers name, date in which they agree to the proposal. At the top of this small signature box I labled PROPOSAL ACCEPTANCE and then with each proposal letter I include 2 pages of legal jargon, dealing with overtime, environmental issues; asbestos and such and all the other junk that we run into. For our office it keeps the paperwork simple and has worked well for several years now.
