Scraper and inserting products in prestashop

I require an experienced developer to build a web scraper and automatically import new product listings from an external online store into my Prestashop e-commerce platform. The target site contains thousands of active products organized into various hierarchical categories.

The developer should construct a scraper using their preferred programming language that is capable of efficiently traversing the target site, parsing relevant product details such as titles, descriptions, images, pricing and attribute values. Duplicate and incomplete product records should be omitted from the data extraction process to ensure clean, high-quality results.

Once scraped, the product listing data needs to be formatted and programmatically inserted into my Prestashop store. This involves creating the corresponding categories and subcategories within Prestashop to mirror the target site's taxonomy, then populating them with new products. Images, pricing and other configurable attribute values must be accurately transferred to each Prestashop product object.

I expect the developer to follow best practices for web crawling ethics and respect any robots.txt directives. The source site must also remain anonymous for contractual reasons. Please provide your typical hourly rate and an estimated
