You may even find a form that has already been completely filled out that will allow you to see exactly how a successful proposal should be written. In most cases the forms will include spaces for you to add pictures, charts and graphs as necessary to explain your proposal in such a manner that makes it much easier for the reader to understand your proposal. In many cases the more detail used to explain a proposal, the better the odds are that you are going to be submitting the winning bid.
The introduction section is the shortest. Start out with a Cover Letter and a Title Page. Keep the Cover Letter brief: simply write a personal introduction to explain who you are and provide your contact information. The Title Page should be exactly what it sounds like: a title that introduces your proposal and provides a clear message about the ideas and/or services you are pitching. Some examples might be "Proposal to Create a New Executive Assistant Position", "Proposed Temporary Services to Benefit the Stuart Corporation", "Executive Search Services Proposed for Jameson Company", or "Suggested Candidates for the Vice President Position".
