Encrypt PDFs with Time Sensitive Password by AndrewScottMusic

I sell PDF downloads on my site andrewscottmusic.com and want to restrict buyers to only being able to open the PDFs 5 times, or to being able to only open the PDF for 5 days after they buy it. To do this job you will probably need a high end digital rights management application... (Budget: $30-$250 USD, Jobs: PDF)
