Build a Facebook Group Email Extractor

I am looking for a freelancer to build an email extractor tool specifically designed for extracting user emails from Facebook groups. The extracted users should be saved in an export format, and the software should be able to run automatically as well. This tool should be able to extract user emails and profile details with ease. It should also be able to extract post contents for further analysis if needed. This is an important tool for automating much of my day-to-day operations, so I am only interested in experienced freelancers who have a proven track record of developing similar tools in the past. Thanks for looking at my project and I look forward to hearing from you soon.
