Amazon PPC Expert needed for Sponsored Products. Amazon Campaign Manager

I'm running a small ecommerce brand on Amazon US selling home & kitchen products. We've had Sponsored Products campaigns running for about 6 months, but our ACOS has crept up to around 38% and I'm not confident the account is structured well. I'm looking for an experienced Amazon PPC Manager to do a focused audit and give me clear, actionable recommendations I can implement myself over the following week. This isn't ongoing management — it's a one-off review. What I need reviewed: - Current Sponsored Products campaign structure (we have 4 active campaigns) - Keyword targeting — auto vs manual, exact vs broad, what's working, what's wasting spend - Negative keyword coverage — I'm sure there are search terms bleeding money - Bid strategy across campaigns — are placements set right, are top-of-search bids optimized - Ad group organization — do we need to restructure into tighter ad groups Deliverable: A written audit (Google Doc or PDF) with: - Top 5-10 specific issues you found - Recommended action for each (what to change, why) - Suggested next-step priorities (what to fix first, second, third) About the account: ~$40k/month in ad spend, 24 SKUs, TACOS target under 15%. I'll share Seller Central / campaign data via Google Doc after we align. Please share 2-3 examples of similar Amazon PPC audits you've done.
