Feed Back Form

Hi,
Once the page is loaded and a user has been on my site for say x seconds I want a small form to appear on the bottom right hand corner like a chat widget asking for a feedback.

If he / she replies great if not it should disappear after a minute.

I searched the net and found many sites that offer that but its a service based business and I don’t think I need that I can have that form emailed to me for my review.

Does anyone know a plugin that does that ?

Cheers,
