URL Query to fill out standard form inputs (not hidden)

Site URL: https://redsteelhvac.com/contact-services

So, I know you can take information from a URL query and easily have it inserted into hidden form fields you create, and I know that there is no easy way to do that with the standard form fields that SquareSpace creates, however I'm wondering if there is any JavaScript that can be or has been written to accomplish this. Basically, we are trying to allow a user that clicks our link from an email campaign to not have to type in all the required information since it's easily attainable from that click. Makes it easier for mobile users to actually submit the form. 

I've seen a few posts on this but no real answer. Any help would be appreciated.
