Fillable Form Submission Challenges

Hello my helpful heros. I created a fillable form in Acrobat and I would like to have a link to it on my web site. That's where the fun begins. Putting up the link is no problem, but I'm running into problems with what happens when it is clicked. For some it opens in the browser using the built-in reader; other open in browser using the Acrobat Reader extension; some download and then ask what to open it with; some download an then immediately open it in the associated app (which may or may not be a browser). The problem is that the behavior of the "SUBMIT" button varies to such an extent that I can't even give instructions - sometimes it does nothing, sometimes it gives an error, sometimes it gives a warning about permissions.

The form is currently on the site: familiarfacesengraving.com under the NMHA link in the left corner with a password of 123456 (not permanent). Note that I have the link currently set to force download.

Is there a more seamless way to submit the form that does not require dealing with so many browser/extension/platform variations? Ideally we would like to receive the completed form in pdf format.
