Customer Profiles - Via FB Page Scraping

I have a specific requirement for "Facebook Profile" scraping. It is the profile of a large TV Channel (Similar to Aaj Tak - [login to view URL]) This is for building customer profiles and executing targeted marketing campaign to the users The Data Points that are needed to be scraped/extracted - If user has "Private profile": User ID, URL of the Profile, Name or Username If user has "Public profile": User ID, URL of the Profile, Name or Username, Email, Mobile Number, Gender, Age, City, etc. (If any of the data point has been made “Public” by the user, then these need to be included) – If user has only made “Email” Public, then pick up the Email ID or if the user has only made “Gender” Public, then include “Gender” only…………. 1. Is the above doable? 2. Need the data in CSV/TXT file for all the 20 Million Likers/Followers – Is this feasible/possible? 3. What will be the cost? 4. How much time will it take?
