Self-Publishing Paperback Formatting Assistance

I'm seeking assistance with formatting my self-help book, "PRINCIPLES OF MIRACLES - Unravelling Their Meaning," for self-publishing as a paperback on Amazon. The book is approximately 26,000 words and currently in Word format. I have already published it as an e-book using Amazon's cover design, but I need help with the paperback formatting.

Key Requirements:
- Format the manuscript to the standard paperback size of 6 x 9 inches.
- Adjust margins and spacing to ensure a professional appearance.
- Add headers and footers for a polished look.
- Format chapters and sections for clarity and ease of reading.

Ideal Skills and Experience:
- Experience with formatting manuscripts for self-publishing on Amazon.
- Proficiency in Microsoft Word and knowledge of paperback formatting standards.
- Attention to detail to ensure the book is visually appealing and easy to read.
- Patience and understanding, as I am not very tech-savvy and have limited financial means.

If you can assist me with this project, I would be very grateful. Your help would mean a lot to me as I navigate the self-publishing process. Thank you for considering my request.
