Catalog Site Product Data Scraper

I'm in need of a professional web scraper who can extract product images and titles from a specific catalog site. The data should be delivered in a JSON file. This is a one-time project, so the scraper should be able to efficiently gather all the necessary information in a single run.

Ideal skills and experience for the job:
- Proficient in web scraping techniques and tools
- Experience with catalog sites in particular
- Able to deliver data in a structured JSON file
- Attention to detail for quality data extraction.
