Lets see if I understand. You want a piece of software that will display a form, get the user's input from the form, and then generate the HTML that you want to display on your site (the actual squeeze page).

Did I understand correctly?

If yes, this is likely a job for a medium to expert PHP programmer. You could specify the job fully and post it for bids on elance or similar sites. You'll get someone to do it for you in no time flat if you offer competitive pay.
