Nannys/babysitters in Barueri,Alphville ?? (São Paulo)

Hi everyone! My husband is being relocated to SP, we are in RS at the moment, Santa Cruz, TINY city so its going to be very nice, if not a little daunting, to be moving somewhere with a little more life! We have a two yr old, who probably wont get straight into day care and I'm going to need to be getting the house unpacked, it would be nice to have someone to watch her while I'm doing the unpacking. Also, with things to do at weekends ( its been a LONG time since we've gone out) we will be looking for a babysitter, I'm quite nervous about leaving her with a stranger, here you can ask the teachers at creche. Does anyone have any recommendations?
Thank you so much! :)
