A formbuilder with predefined variable values

Hi guys,

I’m stuck on something and I really can’t find a descent solution.
The thing is, I would like to have a contactform stuck under each Single template, with a couple of fields, of which one of em has to be the pagetitle of the current page. Preferably I would like it to be READ-Only, unless it’s not stuck in the single template but on a page. I think this would be quite difficult tho.
Does anyone know a good plugin that would work for this? Now, I hardcoded the mailform, but I cant get the mailformscript to work and send it back to the same page with the mailform swapped with a thankyou message.
If you guys don’t know a descent plugin which meets my standard, it would be great if you could help me with the hardcoded script.
