Custom forms for EACH author on my website?

I’m creating a website with MANY (as in 500+) authors, and I want them all to be able to create their own custom forms that they can insert into their posts. (think job applications) I would’ve used Grunion because it can do that, but it won’t save the information into a database, so I have to pass on it.

Is this possible?
This is a vital part of my website, and if it’s not possible, I would truly appreciate it if it could be added in an update.
