Cultural exchange with South/ Central Americans + Hungarian

I looking for someone who just recently (past 1-2 years) come/ lives in Hungary - Budapest and come from South/ Central America (originally - it means: did grow up there, cultural + language/ dialect/ accent). Especially Argentina, Columbia, Mexico. I would like to have some cultural/ language exchange with someone from that geographical region who is interested in Hungarian language (I am a native speaker), and East European culture. As for common tongue we must rely on English.  I am interested things like: taditions/ celebrations Día de los Muertos, common slangs - as perople in reality talk in the streets, and similars. Basically the way of life attitudes and thinking is more important than the language itself.
