Nanny Needed For 3 Children In Austin

We are an Australian family looking for a great nanny for 3 children in Austin for about 15 hours (3 days) per week. We would prefer someone who could help out with light housekeeping and is comfortable driving our minivan. We also need someone who is experienced with managing three young children alone. We mainly need daytime care, but our schedule is very flexible and we can figure out what works best for all of us.
