Every time someone new comes into the office, I do a "usability test". I sit them in front of a computer and give them a task - in my case buying something, in your case filling out a form? - and then I keep quiet and listen to their statements about the site. It has been quite eye-opening to hear what people think of my pride-and-joy, some of it quite unflattering. I then use this input to tweak the site and try again with the next victim.

Maybe you could get someone vaguely in the target market to do this for you? See if your call to action gets them or not?
