Hello,
I'm an experienced PHP developer, that have written many scraping scripts before. I am interested in knowing more about your project, and the page from which it should extract the user data.
The script that I'll make will be made to utilize AJAX, to create a very simple and robust page for the users.
The speed of the script will depend more towards the speed of the server it is uploaded on, and how fast it could connect to it; as the processing of the data by PHP is usually extremely fast.
Let me know if interested, and we could discuss more via chat.
Regards,
Amr
