Travel to Switzerland, NGOs or corporate social programs that can be visited in Geneva

Hello Internations People,
My name is Elizabeth, I come from Argentina and I'll be visiting Geneva with 3 argentineans else next May/June.
I work in a NGO actually and I'd like to know what kind of organizations can I visit there related with education, social development, culture & communication? And if there is someone interesting in making contact with us, in order to communicate what your organization do or to spread networking among us.
It would be interesting to know corporate social responsibility programs too.
Thanks for your consideration,

Elizabeth
