Put Form on Order Landing Page

I'd like to put a small questionarre form on the Order Landing Page asking the customer a couple questions about their shopping experience.

My first idea was to create a form in Website Content, but I can't activate that form using Blocks for the Order Landing Page.

Any idea how to go about this? Ideally the form would be automatically emailed to me, like it would using forms in the Website Content area.

Thanks for your help!

Use an checkout:complete hook to add an html form. Note you will also need to add a controller to process the posted form data.
