Singaporean Family looking for Helper

We are a family of 4 adults (our kids are aged 23 & 26). Occasionally, my elderly mom (85 yo) will stay with us for a week or so. She doesn't need help with anything in particular except to prepare with her meals and bring her on a short walk. 

Our current helper of 18 years is returning home for good.  The main duties are cooking & household chores with a bit of gardening and weekly car washing.  We live in a 2-storey landed with 2 cars (no pets).  We do a lot of baking and cooking so we are looking for someone who enjoys cooking.

We hope to find someone who feel comfortable to be part of our family as our previous helper.
