Shop front facelift (zen cart)

Hello, our shop front looks tired and we would like it looking much fresher / sharper This project involves changing the header graphic for the website and tweaking the template and front page slightly so that the content looks better. We don't want any text content modified - just the look and feel We also hate the fact that there is a large gap between the current header and the content below which we want fixed website address is www dot pi on ee rc ra ft dot com dot au (remove spaces and convert dot to .)
