As others have mentioned getting away from flash would be a good option.
If you still want the rollover effect on your buttons that can be done with css mouseover gifs or even some javascript. Also because the buttons are flash and presumably the link is within the flash this will prove near on impossible for se's to index your site.
Below you've also used images (.gif) for the text - this is an absolute no no! Replace this image with proper <h1> and <p> tags and use the same principle throughout the site using proper html text instead of images and flash. This will do wonders for your indexing and will help your SERPs.
Best of luck.
