Remove landing page and convert simple Flash menu to HTML/Javascript on Joomla website

Hello, We need to do two things on this website: [[login to view URL] 1][1]. remove the landing page 2. convert the Flash menu to HTML/CSS/Javascript cross-browser compatible code. The animation on the first page can be replaced with just a static image. Like this there will be no Flash anymore on the website. It's a simple job that should take only a few hours for someone experimented with Joomla/HTML. We provider FTP to the server. You can work on the live website but make sure the menu is working before to upload it. The website can go offline only a few hours. Thanks
