I need to make a pdf form. This form I would like the customer to only be able to fill it out and save it one time. No printing. The form will be on a usb drive. I then need the same thing but be able to fill or edit the form twice and five times. But still no printing at all. I need to sell a package that would allow me to unlock the file if the customer pays for an upgrade of 1, 2 or 5 more times to edit the file. Is there a way to do this???? Any help would be great.. Please and thank you.
