Nanny / Babysitter One Day Per Week for Two Kids

I'm looking for a Nanny or Babysitter to take care of my son (one) and daughter (four) one day per week - likely a Tuesday or Thursday. Hours approx 7.30 - 4pm. They are both very social, happy kids who have had lots of exposure to daycare / school and babysitters.

We have a park across the road so there are lots of outings and play options nearby.

There will be some very light housework while the baby naps (meal preparation, some laundry, tidying toys as required etc)
