Ms-Style Technical Document Editing

I have several technical documents drafted in Microsoft Word that now need a thorough polish. Every file must follow the Chicago style guide consistently—from headings and citations down to figure captions—while also correcting all grammar, punctuation, and spelling issues. Beyond surface fixes, I want the wording tightened and any outdated or unclear sections revised so the material reads smoothly for a specialist audience.
