be careful, 3500 per month is a rip off.

usual rates range from 800qr all the way to 2300qr live in / full time basis. it really depends on the qualifications you are looking for.

expats tend to pay more as a rule, and as fer as i know the philippine government has a minimium salary req for maids set at 400$ US Dollars per month.

Make sure you Vett very carefully whoever comes into your home.

good luck :)
