I need a software created that will do the following: when you open a PDF file, a popup will appear either immediately or after a certain time period. The visitor has to enter his email address in order to unlock the PDF and continue reading it. If the email address is not entered, the PDF will remain locked. Something similar to viral pdf master . com
I've attached an example PDF of what I am wanting to do. If you have any questions, please send me a PM.

Clarified that this is a programming job and not just a PDF job
