Web Scraper Development for Multi-Website Price Monitoring

I am seeking a skilled developer to create a robust web scraper designed to monitor product prices across four distinct e-commerce websites. The primary objective is to extract specific product information, most importantly prices, from designated URLs on each of these four platforms.

The scraper should be capable of running at scheduled intervals (e.g., Daily or hourly) to efficiently capture and track any price fluctuations. The extracted data needs to be stored in a structured and easily accessible format, such as csv, json, or a simple database, to facilitate subsequent analysis.

Key requirements for this project include:
- Development of a reliable scraping solution for four specified websites.
- Ability to extract product names, prices, and potentially other relevant details (e.g., Availability, URL).
- Implementation of scheduling functionality for automated data collection.
- Data storage in a structured format.
- The solution should ideally be resilient to minor website layout changes and include basic error handling for failed scraping attempts.

Experience with handling dynamic content (JavaScript-rendered pages) and anti-scraping mechanisms is highly valued. The final deliverable will be a functional, well-documented script or application. Please outline your proposed technical approach and the specific technologies you plan to utilize.
