Google Extension for Car Price Comparison

I need a Google Chrome extension that streamlines my car auction decision-making.

The extension should:
- Activate on a specific car auction site
- Use the VIN to fetch and compare prices from another site
- Automatically add predefined fees: transport, auction, and documentation.

Ideal skills and experience:
- Proficiency in developing Google Chrome extensions
- Familiarity with web scraping and API integration
- Experience with car auction and sales websites
- Strong programming skills, particularly in JavaScript

Please provide examples of similar work done.
