Joomla Template / Menu CSS modification

We are in the process of converting a client's site from ASP.NET to Joomla 1.5. We are using a RocketTheme Template (Nexus) as our basis and have completed the majority of the modifications. We need assistance in replicating the clients current menu appearance in our Joomla Template. The client's current menu uses PNG and image files for the text. The new menu with use dynamic text (we have already added their font into the style sheet). The current menu design and structure can be viewed at the top of this page: [login to view URL] You can view the new menu on the development server at: [login to view URL] We need to get this completed in 2 - 3 days. We are running short on time and need to focus on other areas of the site conversion. A fast, professional job will result in additional css work if you are interested. We will provide you will all of the graphic files that you need and will prepare the files for web. All we need you to do is modify the existing menu style sheet and menu programming to closely match the existing site.
