Business Proposal Re-writing

We intend to write a concise business proposal of not more than 6 pages or less. I have already written some stuff but not captivating and persuasive enough. i need someone who can help me rewrite and restructure the proposal. I also want the proposal to include images and data analysis where necessary. More importantly, i want it to be very concise because Nigerians don't like too much reading. We are suppliers of refined petroleum products especially diesel used to power household and in vehicles. We also operate a small gas station where we retail diesel for heavy duty vehicles. We intend to write a proposal to haulage companies whom consume a lot of diesel in their vehicles. Our strategy is to persuade them to pay upfront to our company so that they can enjoy huge discount instead of buying in credit and not getting any discount. thereby benefiting from every liters they purchase from us. We also attract them with the premium quality of our diesel in the midst of rampant adulteration of diesel in the Nigerian market. In addition, the accuracy of our meter is another major point of reference as most gas stations in Nigeria adjust their meter backward and dispense less quantity to customers. We will also need to do a cost benefit analysis of doing business with us and others. Furthermore, there is need for cost benefit analysis and data/graphical representation Our objective is to drive volume sales by attracting customers with what others do not offer. therefore, we need a very persuasive and sincere write up.
