Wordpress plugin

[aditd]

Hope I found the best place for this topic.

Looking for a plugin that will do me a fix section on the template. It should look like the chat window ( that appears on the sites with live chat available ) that follows you even if you scroll down a page.
Something like ( Customer Support, Buy Online, Safe Online Shopping | Plimus )

But I don't want a live chat window ... I want to edit that window and that should work with html ( so that I can put whatever I want in that section ).

Have any idea of something like that?

Several WordPress themes like Thesis (paid) and probably some of the free ones have that feature built in.
