For the very first move I would remove the flash version, or would make that one optional, not the html, I needed to wait around 20 secs to see what is your website about. Visitors won’t wait that long, believe me. They come, read the headlines, if there is something they like then they click, if there is nothing, they just press the back button or close the window. From my experience animations, landing pages which requires clicks to get to the site content is not successful, internet users are impatient folks, you need to push your best content into their face at once when they land on your pages. (i.e. show them what you have when they arrive, don’t force them to wait/click/subscribe just to reach your content, otherwise they will leave very fast 
From the search engines point of view, flash is hard to index (though Google says he can spider it partially – but what if not?), SE spiders have much easier time with plain pure html to crawl. More content to crawl = more of your pages in their index = more visitors.
Also on the html version of the page, the banners, pictures cannot be clicked. People love pictures, and they love clickable pictures more. I would make all those pictures clickable.
These were my first impressions when i landed on your website, I hope it helps :hattip:
