Make an automated scraping script

I am looking for scraping script to import data from different e-commerce sites and then export them and map them through a WooCommerce REST API into my e-commerce site with the ability to run the script in automated way through corn jobs. The data I am looking for are related to products, such as: Brand, Product name, Quantity, Price, description, photos (image URLs), sizes, colors, SKU, etc. The script should support multi-threading, and proxy rotating (as an option that I simply can disable or enable from the script). • Project scope: Front-end is WP Woo-Commerce store (the shop is online already) which will show the scrapped product list from multiple markets. Back-end :- Custom (python or php) based extension scrapped, filter, store, and map the scrapped product to front-end and make dynamic e-commerce store available to end user. The script should be able to map the listing on store, dynamically updated the product price and inventory based on 3rd party market place product updates, with ability to process over 25,000 products daily from all agreed market places. For product pricing, there will be a different price formula for each category in each scraped site. Kindly PM me for more details and for a sample data set.
