If you live in Brazil and want to help an AFS exchange student?

I am an exchange student with AFS from California into Brazil. I love your country but I was put into the state of Mato Grosso de Sul, which is land locked, and I live in a very small city. I want to move to a big city on the coast, such as Sao Paulo, Forteleza, Salvador etc. and I can only do so If I have a family there that wants to take me in. I understand how strange this is but I am desperate to get to the ocean. I am just asking. If you think you would be intrested in hosting an exchange student for a while I will supply you with the information needed and be forever thankful that you gave me this oppurtunity to live near the coast. Obrigado.
