Hello,
I have done projects which parses PDF documents, I have myself developed classes/scripts which can parse PDF to simple text, then using REGEX (Regular Expression) these applications can read useful data from it.
I have also worked on SMTP to verify email addresses and can develop scripts to send clean emails with proper commands (using Curl, etc). I have also done cron jobs to download PDFs from open websites. I can show you my works if you want.
I have few questions regarding your projects, if you want you can contact me over chat to discuss this project of yours.
Thanks
Meeshal k
