Convert small website from html/flash to html/javascript

Hello, We would like to convert the existing website [login to view URL] from html+flash to html+javascript The aim is to completely get rid of the flash and be compatible with smartphones and tablets as well as regular PC browsers (at least IE8+, firefox, chrome, safari). The website is basically one big flash animation that is also used to navigate the site, a few html pages (that probably do not need to be changed much) and some audio. We have the source of the flash animation. We only wish the full version of the animation, we do not need the "light" version ([login to view URL]) to be converted. We will prefer solutions using the jquery library, but we will consider other options if needed. We would like the navigation to change the URL based on the page viewed (for example [login to view URL], but with the correct template) so that we can make links directly to any given page. Please give us examples of your work and tell us how much time would it take you to convert our site.
