How does one create a DIV that appears in the bottom corner of the window (after a set amount of time)?
===

I would like to create a "LiveChat Offering" pop-up that appears in the bottom of the screen after our visitors arrive at a specific page, and have been on that page for say 30 seconds or so. I would like to keep the code jQuery/CSS if at all possible.

    <script type="text/javascript" src='http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js'></script>
    <script type="text/javascript">Some jQuery that will change the 'display:hidden;' to 'display:block;' on the DIV after 30 seconds</script>

    <div id="live-chat" style="position:absolute;bottom:0px; right:100px;z-index:5;display:none;>
     <h4>Need Help?</h4>
     <p>Click the link below for assistance</p>
     <a href="live-chat.php">Chat with a salesman</a>
    </div>
