Drupal 7 - Twitter like view module

Looking for a Drupal module developer expert with high level of experience in Jquery UI design. We want a Module for Drupal 7 that would generate a twitter-like view to display nodes. It has to be full JQuery / AJAX, no page load is allowed, and most of the user actions will update the URL anchor so that the URL can be copy / pasted and display the same. The module will also regularly scan the DB for new nodes and display an alert for them (like on twitter). You are asked to rely on existing Drupal modules and use as much as you can their functions or hooks. We will provide a content-type exported with features. You should deliver a Drupal 7 module. All the configurations of the UI for other modules should be done within this custom module. You can use features to export configurations. The theme will be applied in a second step with a new project but you should already integrate a basic theme as a base. You must use all Drupal base system and functionalities: content-types, views, feeds, nodes. You need to be able to provide an invoice in English (french or spanish) for the full amount of the project. On PM give examples of JQuery / AJAX sites you have done or that you like. Ergonomic is the main key. Thanks and best regards
