UK English Word Document Proofreading

I have a Word document that must be polished for spelling and grammar before I convert it to PDF. All text needs to follow UK English conventions—no American spellings, please. I don’t need style changes, wording improvements, or layout tweaks; this is strictly a final linguistic check.

Once finished, return a clean, corrected Word file with every error already fixed and no track-changes or comment balloons showing. The document should be ready for immediate export to PDF the moment I receive it.
