Seeking child-carer/housekeeper 1-2 days a week (São Paulo)

Hi everyone,
We´re moving from Peru to Brazil at the end of July and will be looking for someone to help out at home doing some basic cleaning and child-minding Protected content per week. Does anyone have recommendations? Also what is the current rate? My son is 8 and speaks Spanish and English but I'm really keen on just having someone who speaks only Portuguese...
Thanks,
Pamela.
