Proof-read a 35 page report and edit for publication

I need you to proof-read and edit a technical report (well, not TOO technical - it's meant to be read by a well-educated general audience). What's important to me is NOT just that you correct any grammar and spelling errors (of which there are few, if any) but to actually correct the flow, ensure consistent style, and improve the readability of the text to a professional, publication-ready standard.

I also need you to re-write the entire 1st page (the introduction) to make it catchier and to build anticipation for the remaining of the text.

I will provide a Word document with the original, and will expect two documents back: one with all the changes marked, and one with just the final result.

In your proposal, please tell me WHY you think you're the right person for this job, and also approximately how long you think this would take you.
