I follow a fairly standard approach:
Letter explaining following proposal;
- Thanks for opportunity;
- Listening to your concerns I can see x, y, and z is critical in this project
- The proposal is broken into the following sections;
1) Intro (state the problem/challenge);
2) Proposed solution (overview);
3) Scope of work (more detailed);
4) Assumptions (critical elements that define what client is responsible for/what you are responsible for);
5) Schedule & Fees
a) How change orders are handled;
b) Payment schedule
6) Authorization
a) client signature/date with clause
Client agrees to pay contractor/company x based on the payment schedule in section 5. Final payment is due x days after completion of Section 3 scope of work (or immediately upon completion);
A note about proposals. Guage the size of the project before taking extensive time to give a proposal. For small projects (you determine), do not create multiple page proposals. A simple 1 page letter estimate is adequate.
You don't want to spend 2 days creating a proposal for even 1 week of work. I use a rule. If the project is less than 1 month in duration, I give a 1 page letter with authorization.
Hope this is somewhat helpful. Matthew Moran
