KDP Non-Fiction Book Editing

I need a comprehensive edit for a non-fiction biography book before I publish it on KDP.

Key requirements:
- Proofreading to correct grammar and punctuation errors
- Copy editing for clarity and consistency
- Developmental editing to enhance structure and flow

Ideal Skills and Experience:
- Experience with KDP publishing
- Strong background in editing non-fiction, specifically biographies
- Attention to detail and excellent command of the English language
- Ability to provide constructive feedback and suggestions for improvement

Freelancers with a portfolio demonstrating similar work would be preferred.
