American English Editor for Nonfiction Book Translation Polish

I am seeking a highly skilled and detail-oriented editor, preferably a native or near-native American English speaker, to perform a final polish pass on a translated nonfiction book titled 'The Ten Laws of Deep Sleep'. This psychology-based self-help book, originally written in Spanish by a clinical psychologist, has undergone AI-assisted translation and a subsequent colloquial editing pass. The project now requires a final human review to ensure natural, fluent American English.

The scope of work includes:
- A comprehensive read-through of the manuscript, approximately 15,000–18,000 words.
- Identifying and rewriting any phrasing that appears AI-generated, stiff, overly formal, or unnatural for a conversational nonfiction style.
- Specific attention to common AI writing patterns, such as repetitive sentence structures, overused transition words (e.g., 'Moreover', 'furthermore', 'notably'), inflated vocabulary (e.g., 'Delve', 'tapestry', 'underscore', 'foster'), rhetorical triads for emphasis, and generic 'it's not just X, it's Y' constructions.
- Performing light copyediting for grammar, flow, and consistency. Please note this is not a developmental edit; the book's structure and content are considered final.
- Ensuring the preservation of the author's warm, direct, and conversational voice, avoiding a clinical textbook tone.
- Flagging any sections where the meaning is unclear or where a native speaker's ear detects awkward phrasing that doesn't quite resonate. Fixing these flagged sections is not strictly required but identifying them is crucial.
