Convert site to wordpress, script install & widgets required

Hi we We require our existing site to be converted to wordpress. The site is a sports tipping website whereby users select outcomes of matches through logging in to their own admin panel. These selections are then ticked won/lost/void by ourselves once the event has passed. We need the new wordpress blog to be integrated with our backend, with widgets created for the different sections of our site, and sections hardcoded in. At the moment we need the database/wordpress integration...we are not looking for a new design.. PM for more info!
