Hello,
I've experience in writing PHP scripts to scrape data from websites.
The scrips have the ability to utilize proxies so they could go undetected. To ensure data is grabbed in speed, the scrips are uploaded on multiple servers, and work parallel to one another.
Data extracted could be exported to an excel worksheet, a CSS file, or a MySQL database.
If you let me know more about the 3 websites you want to scrape, I could offer a more realistic bid and delivery time.
Let me know through chat if you're interested, and we could talk more.
Regards,
Amr
