Hi,
Let me help you with this project.
I have experience with web scraping sites like Amazon, Ebay, Abebooks, TripAdvisor and many other ecommerce sites.
I can build the scraper using python so it can be run on server if needed.
Google chrome scraping is also available if site needs login or contains javascript.
Please send me the URL of the websites and I will build the scraper right away.
Looking forward to hearing from you.
Regards,
Susanto
