Amazon KDP Ads + Listing Optimization for Already-Launched Nonfiction Book

I have an already-launched self-published nonfiction book on intimacy, attachment, selfhood, and relationship patterns. I need someone experienced with Amazon KDP and Amazon Ads to set up a small, low-budget Sponsored Products campaign structure for the book. I am not looking for general book marketing, social media promotion, paid reviews, fake engagement, mass blasts, bestseller promises, or vague visibility packages. **Deliverables:** 1. Briefly review my Amazon listing and flag any major issues before ads begin. 2. Validate keyword and ASIN/product targets using Amazon Ads experience and/or tools such as Publisher Rocket. 3. Set up a small Sponsored Products structure inside Amazon Ads, likely: * 1 automatic discovery campaign * 1 manual exact keyword campaign * 1 manual phrase keyword campaign * 1 product/ASIN targeting campaign * optional defensive campaign for author/book title 4. Recommend starting bids and daily budgets appropriate for a low-priced Kindle book. 5. Explain what data I should watch during the first 2–4 weeks, including when to pause terms, add negatives, lower bids, or move terms into exact match. The Kindle price is low, so CPC discipline matters. I need someone who understands how to avoid wasting money on clicks that cannot realistically become profitable. **Budget:** $200 fixed price for setup and written recommendations. Please answer: 1. Have you set up Amazon Ads for self-published nonfiction books? 2. Do you use Publisher Rocket or another keyword/category research tool? 3. How would you structure ads for a $3.99 Kindle book without letting CPC destroy profitability? 4. Would you be willing to set up the campaigns directly in Amazon Ads using targets I approve first?
