Domestic helper

Hi,

I am looking for someone to do housekeeping, cleaning, laundry, marketing, cooking and washing of car. I have 2 teenage children and we live in a house and I am working  from home sometimes. . The helper should be able to work independently and help manage the teens if I’m away. 
we may get a pet dog in the future and the helper should be comfortable to look after one if we decide to.

we are a christian family. The helper may have every Sunday off but occasionally we may need to change the off days to another day if we have an event.
