Well, theres hardly any opening for volunteerism over here, every single expatriate works for money, and the locals, well lets not kid ourselves.

So, in return, the employers/companies don't expect to get help without paying. And if someone offers to help, the offer is taken with a huge amount of doubt, as if that person is after their company jewels.

I would recommend Northwestern University at QF, maybe you can atleast get some decent appreciation for your generous offer, plus some decent company.
