Need javascript for scolling content

Hello, I need to write javascript code that will make a certain div content appear on top of the page when user scrolls down. If you take a look at our site - [login to view URL] you will see "Receive instant quote" column on the right side. Currently, when you scroll down, that content is static and not visible when you go below the fold. I want that content to always be visible even if the user scrolls all the way to the bottom. i have attached the screen shot of the content that should be always visible when user scrolls down.
