I don't know about spending such an absurd amount of money, but Richard Feynman is a mighty fine choice.
I read that talking to him can be quite frustrating. Because he can be just so far ahead of you... Can't remember who wrote it, but it went like this: "There is the ordinary genius, and the extraordinary genius. The ordinary genius is just like you and me, only much, much better. The extraordinary genius is different. " And Feynman is said to fall into that category.
