Redesign pop up window to more moder design and implement automatic pop up for 1st time users.(repost)

We would like the 'take a trial' pop up window on this page redesigned to make it more modern and attractive. : [login to view URL], on all 5 language pages. An example can be seen on [login to view URL] Also we would like a system where the pop up window appears automatically when a new user enters the site, but only for unique visitors. we do NOT want this to occur for our regular customers. We also want the free trial button to be added to all the price lists on the different language pages. Many thanks. James.
