Weekly care - Saturdays

We're searching for a permanent care solution on Saturdays for 1.5 kids (our 2yo daughter each week and my 8yo son every second week when he isn't at his dads)

I'm about to start working Saturdays, and my husband already does, so ideally looking to lock someone in each week likely 8am-4pm, but could be more like 8am-12/2pm once I get settled in and can get away with half days.

Bonus if you can help a mum out with some ironing & washing etc, but not a necessity.
