Amazon book manager — listing, inventory & ads for profitability

We've published a book on Amazon — Breadcrumbs: A Path to Set-Apart Living, a faith/Scripture-based book for a Torah-observant and Hebrew Roots audience. We're looking for one experienced person to take over and run the entire Amazon side of this book. The goal is simple: make it genuinely profitable. What "profitable" means here: net profit to us after ALL costs — your fees, ad spend, print and fulfillment, and Amazon's cut. We are not interested in top-line sales that lose money. We want the book to make real money after everything is paid. Scope of the role: Fix availability / Buy Box — right now the listing does not have an active Buy Now / Add to Cart button. Diagnose why and get it fully buyable. Manage inventory — keep the book in stock and available (KDP print/ebook and any fulfillment settings) so it never goes unavailable. Optimize the listing — title, subtitle, description, backend keywords, categories, and A+ content so it ranks for the right terms and converts browsers into buyers. Run profitable ad campaigns — build and manage Amazon Sponsored Products and other relevant ads, manage keywords and bids, and keep spend efficient. Report monthly on units sold, ad spend, ACOS/TACOS, and net profitability, and adjust to protect margin. This is a faith-based title for a specific audience, so experience with niche or values-driven book marketing is a plus, but strong hands-on Amazon KDP, Seller Central, and Amazon Ads management focused on profitable growth is what matters most. Please only apply if, after looking at this book, you genuinely believe you can run it to real net profitability — and tell us briefly why. Include 1–2 examples of Amazon book accounts or campaigns you've managed, with profitability results if you can show them.
