Self-Help Book Proofing & Edit

I have completed a non-fiction, self-help manuscript and now need a fresh, professional eye to bring it to publish-ready quality. I’m looking for both content editing and meticulous proofreading: tighten the structure where it drifts, flag sections that need clearer examples or smoother transitions, and correct every grammar, punctuation, and consistency issue you spot. I’ll send the full draft in Word so you can track changes. When you return it, I’d like two files—one with visible mark-ups and comments, and a clean version with all edits accepted—plus a brief editorial memo that explains any larger structural or tone suggestions you think will raise the impact for readers. If you’re experienced with self-help titles and comfortable balancing an encouraging voice with clear, actionable advice, I’d love to work together. The book is 12,000 words so please quote on that basis Please estimate the job hours required.
