This is the PP again. If you are set on staying here and have $$$ then there are banks that specialize in highly educated donors. I came across Golden Egg (LOL!) via a Google search before:

I am sure that there are others which are similar.
Also as another poster mentioned, direct recruitment on the campuses of elite schools is common. On the Columbia campus 17 years ago I used to see flyers from the intended parents offering many thousands of dollars to young women who fit very specific profiles including but not limited to height, weight, health status, ethnicity, major field of study, GPA, SAT scores, sports, musical ability, hair texture... any and everything!
