I, too, follow a very specific RFP format. I always include a cover page with my logo, date submitted and the RFP number and title. And I always PDF the RFP - for whatever reason, people see PDF and think professional.
My first page is my business philosophy (what drives me to follow good marketing practices and why this is good for the client). It usually mirrors whatever you have on your website.
Second page is a brief biography of everyone that will work on the project. Relevant experience is good, but only the information that will help this particular project.
Third page is the plan to address whatever their RFP request is. Includes dates and project milestones where necessary. I also include anticipated hours for each task with a completion date.
Fourth page is language about project overages, unanticipated (by them) project details, if there is a website or newsletter copy involved, how many iterations they get to change their mind about the content, and what the hourly fee is for overages caused by the client.
Fifth page is the terms of the contract. For example, I expect payment for services at a percentage upfront and rendered at net 45 days. When I work off an RFP, I am typically working on a PO, so they expect that they will pay some monthly.
Last page is the signature page, so they can send back a signed contract.
