Countdown and Purchases counter component for Virtuemart

I need a component designed for my Joomla based website that will link up with Virtuemart to perform multiple tasks. It will need to be able to allow me to set a time limit on how long a good is available for, showing a timer on the frontpage for how long the deal is available for. It will also need to have a heat bar, showing how many purchases have been made. The component will have to be easy to use and look tidy when displayed on the front page. This is a exemple of counter and countdown: [login to view URL]
