Clone the functionality of a Viral Traffic Script

We're looking for a developer able to take the functionality of the following site... [login to view URL] ...clone it (AND re-develop it so that it brings the app into the 21 century... i.e. using HTML 5, jQuery etc). We don't want any design work to be carried out. Just the bare bones of the application. (but we will require that all elements are tagged with class tags, so we can easily update the design with CSS once we come to skinning the app. A simple back end management system will be needed too. Please take a look through the site, familiarize yourself with it and contact us with a proposal. (Especially specifying exactly what you would do to bring it into the 21th Century). Copy and pasted PM's will not be considered. We're looking for candidates that have a good knowledge of the english language. Are professional and willing to communicate on a daily basis. Looking forward to seeing your bids/proposals.
