Extract Data from Facebook

I am looking for a good and reliable VA that extract data from Facebook from certain groups. I want to be able to extract personal information like full name and email addresses using automated tools like scripts or online tools. I am open to experts for this type of job. I expect candidates to have this experience previously. Price is negotiable based on the data you can scrape for me and it has to be automated and not manual ways of doing it. Thank you and look forward to hearing form you.
