Domestic help Singapore - house care, cooking

We are a family of 6. Our children are 19, 16, 14 and 11. We stay in a landed 2.5 storey house with a side garden. Daily chores include house cleaning, cooking 2 meals a day, groceries shopping, planning of meal, cleaning of garden leaves, feeding fish, laundry, ironing, car wash. Sunday off, own room. Our children do not need much care, so mostly is cooking and cleaning. Occasional entertaining. Before covid, our church cell group comes to our house weekly for bible study. Some help in cleaning after entertaining is necessary.
