Web Page Upgrade (flash or html5)

Hi I would like to upgrade existing flash web page. It is very simple. It is only one page with gallery & scrolling thumbnails. It is written in action script 2 (player 9). It is simple xml driven image gallery with thumbnails scroll at the bottom. I would like to add the same functionality for video from you tube. This xml driven gallery is now only for images (thumbs and big). So we should add button for video & images to switch between scroll for images vs. video. It has to be xml driven, so we can easily add and change video as we can do it with images. I provide source flv file and design. If you are interested I will send you design + source flv to see details ===================================================================== HTML5 coders would you be so kind and answer my question below ===================================================================== I did not decide yet which one should I take...flash vs. html5 version? Have any ideas? For all Xhtml/HTML5 coders...how much would you charge for the same site in Xhtml/HTML5? Regards, Peter
