Comprehensive Copy Edit 5k+ Manuscript

I have a document exceeding 5,000 words that now needs a thorough copy edit. Your task is to polish every sentence for grammar, spelling, punctuation, consistency of style, and flow while preserving my original voice.

Key expectations:
• Work directly in Microsoft Word, using Track Changes so I can see every adjustment.
• Flag any unclear passages or factual inconsistencies with concise comments.
• Deliver two files: one with Track Changes on, one clean copy ready for publication.

Please include a brief note on your turnaround time and any relevant experience handling long-form texts.
