Domestic Helper

I need a live-in helper mainly to look after my elderly mother and do housework. Some descriptions of the tasks:

1. Take care of an elderly woman (ah mah) in her 80s. She walks with walking stick and mostly watch TV on the sofa.
2. Do housework to keep the place clean (a small apartment with 3 bed-rooms)
3. Wash car (weekly)
4. Cooking - not much (simple meals for 2 persons)
5. sometimes an aunt will come and stay with us for a few days, be helpful to her.

The helper will share room with ah mah. I am fine with 2 off-days a month. 

*** Those who have patience with old folks and are kind-hearted in nature are most welcome. 

*** I'm not familiar with the documentation required for candidates from overseas, so it helps if you are already living in Singapore. Thanks you.
