VERY simple jQuery popup/chatbox (jQuery/css)

Hi - I am just looking for a VERY simple jQuery/mySQL chatbox. I expect this only to be a $5-$15 project for someone that knows what they are doing. In fact - VERY similar to what you see here on the freelancer site, but just the jQuery. a) Minimize/maximize button. I should be able to customize the height of the box easily via css. b) Should hover bottom right hand corner. b) jQuery just polls a script (that I can set in ms, i.e., every 1000ms) - to 'refresh' the contents of the box. Native English speakers (or proficient) in English, and ideally European or USA/Canada/UK/Australia based are welcome to apply.
