Personal Letter Grammar Proofreading

I have a short personal letter drafted in Microsoft Word that needs a careful read-through for grammar, spelling, and punctuation only—no rewriting or style changes, just a clean, error-free text that still sounds like me. Please work directly in the .docx file, using Track Changes so I can see every correction, and include a second version with all edits accepted for easy sending. A quick turnaround is appreciated; the letter is fewer than two pages.
