convert flash site to joomla

We need to recreate an existing site to a Joomla site OR SOMETHING THAT CAN BE UPDATED WITHOUT FLASH. The existing site is at www.jdtyre.com. We love this flip effect, but find the site to cumbersome to update. We would like something easier to update, for example all the images on the home page are in a folder called \homepage, and all the images for gallery 1 are in a folder called \gallery1, etc. Please contact with any questions and how you would plan to implement this, most importantly how the updates would be handled. Thanks in advance.
