Video with music for you tube

We want to start in the near future our project - a worldwide webbased service. For that reason we need a video that we can post on youtube to get staff and intruduce ourself. We guess its a nice idea to compose a music track (dance/rap) and let different people sing/rap in thier own language a part of it. The idea of songtext will be delivered. You may create the video from different "webvideos" from singers and mix them with animated Graphics. At least the video must be energetic, funny and entertaining. The quality must be professional. The goal is to get the people interested to work for us. We need languages like, englisch, hindi, russian, arabic, spain, france, china, portuguese, german, bengalese, japan, korean and more....
