Consistent Formatting for 120,000 Word eBook

I have a 120,000-word book with 34 chapters that needs to be formatted uniformly for an eBook. Please ensure the formatting is consistent throughout, with the same number of lines between sentences, all the same text font, and so forth. I'm not sure about "Headings being formatted the same." No. Chapter titles, etc., would be larger, bolder font. All the words in the book should be formatted the same.

Key requirements:
- Text format: Calibri
- Spacing: Double spacing
- Headings/Subheadings: All need to be formatted the same
- Chapter Titles: Each chapter title should be bold and centered.
- Paragraph Indentation: First line of each paragraph should be indented.
- Table of Contents: Create a clickable table of contents for easier navigation.
- Footnotes: Footnotes should be formatted in 10pt Calibri and single spaced.
- Margins: Ensure all pages have uniform margins.
- Page Numbers: Ensure sequential page numbers are correct and consistent.
- Image Placement: Any images should be centered and have consistent padding.
- File Format: Deliver the final eBook in both ePub and PDF formats.

Ideal skills include:
- Proficiency in eBook formatting
- Attention to detail for consistent layout
- Familiarity with Calibri font and double spacing

The eBook should be formatted in a common format.
