Comprehensive Grammar Proofreading

I have a single document that runs well beyond 5,000 words and I need every sentence examined with a sharp editorial eye. Your brief is to catch the usual suspects—spelling, punctuation, agreement errors—while also flagging awkward phrasing or wordiness and leaving clear, actionable suggestions on how to tighten the prose. I do NOT need wholesale rewriting; instead, I want to see precisely what you would change and why, so I can approve or reject each edit with confidence. Please work in a platform that supports inline change tracking (Microsoft Word Track Changes or Google Docs Suggestion mode) and keep all edits transparent. A light style‐guide touch is welcome if you notice consistency issues (Oxford commas, capitalisation schemes, number formatting), but maintain the original voice wherever possible. Deliverables • Mark-up file with every correction and comment visible • Clean, final version after all accepted changes • Brief summary of frequent issues you observed (so I can avoid them next time) Turnaround is flexible for quality work, yet let me know your realistic timeframe in your proposal.
