Hey Tom,
Thank you for reaching out to us!
Before we begin, just to set expectations, the scope of our support is mostly to get our customers started on the right track and to help them in case of issues. We unfortunately do not provide complete support for customizations like this one.
To help you get started, I believe the simplest way to achieve what you want is by moving the form div via jQuery:

This is just an example based on the divs I’ve found in your site (you may need to adjust it if the selectors are incorrect). You can add this code in your theme’s functions.php file (without the PHP opening tag).
I hope this helps you to get started! If you have any other questions at all please feel free to let me know and Iād be happy to help as best I can!
Cheers,
Patricia
