Nanny to 10 yr old boy

I'm looking for a casual nanny for my son, 10 yrs old. His school is in Wahroonga, WPS and our home is behind Abbotsleigh Senior school.

Looking for someone to send him to school on certain days of the week (Wed +/- Fri am ) , pick him from school (Tuesday, Thurs & Friday) bring him home, assist with afternoon tea and help with simple home tasks (laundry - drying or folding clothes, cleaning island table top if used and simple house keeping - we have cleaners that come once a fortnight so nothing major). Work hours as mentioned above and happy to clarify further on EOI.
