Aerospace Book Editing

I’m looking for a professional editor to help finalize a non-fiction book in 9 structured sections, totaling approximately 300 to 310 pages. The book is already written and mostly formatted. I need help with:

✅ Reviewing and inserting accurate chapter numbers
✅ Ensuring consistency across section titles, fonts, sizes, headers
✅ Cleaning up the Table of Contents to match the actual content
✅ Light proofreading and formatting where needed
✅ Ensuring a clean, print-ready Word document (6x9 layout)
I Need:
Attention to detail (chapter numbering, formatting, spacing)
Basic layout polish (no design or illustrations)
Light proofreading (grammar/syntax already mostly reviewed)
Experience with nonfiction or technical books is a plus

Budget:
This is a limited budget project, so I’m looking for affordable but reliable support — ideally from a freelancer who’s efficient and detail-oriented.
