Editor for Short Essays Collection

I’m looking for a copy editor and editorial assessment for a completed nonfiction manuscript: On Purpose: Designing, Protecting, and Passing On the Life You Built. It’s a collection of 15 short essays (~550 words each, ~8,250 words total) on wealth transfer, legacy, and family communication, written for high-net-worth and ultra-high-net-worth families. Each chapter follows a consistent structure and stands alone. This is a personal project — the book will be printed and given as a gift to clients and contacts, not sold. I want a polished, professional result. Scope: copy editing (grammar, clarity, consistency, flow) and editorial assessment (does the argument land, are there gaps, is the voice consistent). Structure is locked — not a developmental edit. Ideal candidates have experience with financial services or wealth management content and a direct, warm, non-jargon voice. Please include relevant samples and your rate (flat fee preferred over per-word given the length).
