Design new site using data from old site in Drupal

we are a charity organisation and need to move create a new website in Drupal CMS. our current website is built using static pages and is already running. The new site needs to implement (using a desired theme graphic for homepage, that will be provided) the following drupal modules - site search, shopping cart, discussion forum, private message,events calendar, opinion poll etc. the standard drupal modules. Another thing required is ip-homing(for region specific re-direction of users). Capability to setup a multilingual site would be a plus favouring selection.
