build and review a business proposal document

Hi! I am looking for someone to help me build and review a sales proposal document. I have an existing document that I need reviewed, and I'm expecting the project to include a high level overview. The sales proposal document should be well-written and organized and provide an overall strategy for my business. Additionally, the project should include a review on the grammar and business language used, Chart/workflow for phase 1 after reviewing and editing the steps,. The end result should be a comprehensive document that outlines my business goals, and the steps toward achieving them.
