Templates save you money: If you use a royalty_free template, it likely costs less than hiring someone to create a custom graphics package for you. You could easily spend hundreds (or possibly thousands) of pounds on a custom motion graphics opening, for example, whereas you can frequently purchase a royalty_free template for under £200. Of course, the royalty_free template isn't as unique as a totally custom template, but it definitely costs less, and you could always customize the royalty_free template to make it more unique for you.
After you collect the basic facts about the party you are pitching to, writing the proposal will be a fairly straightforward process. All proposals follow a similar four_section structure: 1) introduction, 2) summary of the situation and needs, followed by 3) descriptions of the idea or the goods, personnel, or services you are offering, including relevant details and costs. Then you conclude with 4) all the information you need to persuade the proposal reader to trust you, such as your experience, credentials, and capabilities.
