I have this stakeholders dinner and would like Sir Richard Branson to be the chief speaker?

I belong to this International Student organisation called AIESEC, we are based in 100 countries with our head office currently in rotterdam, I am Ugandan and at the just concluded International Aiesec Presidents meeting Uganda emerged in the African region as the best country that has achieved so much in a short perion od time. so to recognise all the companies and people whi have supported us through the years we are going to have our 15th anniversary stakeholders dinner in June 2011. Its the reason why we would like Sir Richard Branson to grace our occion as chief speaker.
