So this was built on Keenforms, an app I built. It's a form builder with a no code rules engine. You can try it for free, would love feedback. Would love to help you build something if you had an idea.
You can sign up for an account, create a form with a drag and drop interface and then add rules to set values, etc. You can also generate dynamic HTML with a form rule and a bootstrap class, sticky footer.
I would love to do that, but it will take some time. Building from scratch all over again would be a lot of work, maybe I'd give a tour of how it was built, show all the rules?
Can you give us some background? What was the experience like? Have you used other tools?
Edit: Ah, I see that you created the site, so you must have talked about that before. Is there a post you'd recommend to satisfy my curiosity?
