Amazon Competitor Monitoring Bot

I need a small, reliable bot that runs directly in Chrome—preferably built with UI.Vision macros—to track my competitors on all Amazon EU marketplaces for the 20 dietary-supplement ASINs in my catalogue. Each run must collect a few data points from every competing listing: e.g. the current price, the latest customer-review count and rating, the name of the active seller or sellers.

Schedule
• The macro should execute automatically twice a week (Tuesday and Thursday).
• A fully working version of the tool has to be in my hands within three days of project start.

Data handling
After every run, export the scrape into an Excel file (I'll provide) that I can import into Google Sheets. I also want a concise analytical tab (or separate sheet) that highlights week-on-week price changes, rating shifts and any seller swaps, so I can spot trends without digging through raw rows.

Deliverables
1. Chrome-ready UI.Vision macro set (or equivalent) packaged with clear setup instructions.
2. Twice-weekly Excel/Sheets report containing:
– Raw scrape (pricing, reviews, seller).
– Calculated deltas and brief insights.
3. Ongoing hand-off process so the macro can be updated easily if Amazon alters its page layout.

Payment will be split between a one-off milestone for the tool itself and a smaller recurring release for each scheduled report. I’m ready to kick off immediately; please tell me how quickly you can hit the three-day build deadline and outline any Amazon anti-bot precautions you intend to use.
