nanny needed in Copacabana (Rio de Janeiro)

Hi, we are a little family with a one year young boy living in Rio since couple of months and we are looking for a good and trustable nanny and help in household in one person (on contract with all social benefits). If you know somebody, or maybe you know a family who leaves the country and doesn’t need their nanny anymore, or maybe there is somebody who knows somebody… However, I would be glad about any tip.
P.S. we live in Copacabana, Rua República do Peru
