Hi there!
I have read and understood that you want user details (first & last name, Facebook id, etc.) from Facebook groups.
I will do this for $15(CAD).
I am highly skilled in Facebook, Instagram, Web Searching, Web Scraping, etc. and I will start working right away.
I can provide a sample, and make sure you get the best value for your money. Please initiate a private message so that we can discuss further and start working right away.
Thank you, and have a great day!
Shubham
