Basically he needs $400 million, which is less than the cost of one shuttle launch. It'll be a vehicle that can lift four people to earth orbit, go to the ISS or meet up with a moon-bound CEV once that NASA plan gets underway, or do something else. Each launch will cost only $20 million. And he can have it ready for first launch by 2008.
