Hi,
I am Ashok Kr Sharma. Working with Website Designing & Software Developement for couple of years.
I already had created such application for one of my client which generates a PDF file after submitting input from the front end.
What is the site address where you want embed this application, let me have a look.
Should be able to help you.
Let's discuss.
Sincerely,
Ashok Kr. Sharma
