Amazon book expert

I have a finished ~57,000-word nonfiction manuscript and need an experienced KDP self-publishing specialist to take it from Word doc to live, professionally launched book on Amazon. Scope includes: interior formatting/typesetting for both ebook and paperback, ISBN assignment, a professional cover design (front, spine, back with blurb), writing/optimizing the Amazon listing (title, subtitle, description, keywords, and category selection), and complete setup and upload through Kindle Direct Publishing. I’d also like a launch strategy aimed at ranking in relevant niche categories — please describe your approach to pricing, category/keyword targeting, reviews, and launch-week promotion. Note: I’m only interested in legitimate, Amazon-TOS-compliant methods — no paid/fake reviews or rank manipulation. Please share your portfolio of published titles you’ve launched, which of these services you handle in-house vs. subcontract, your turnaround time, and your pricing (flat or milestone-based). Bonus if you have experience with business/professional nonfiction.
