Casual Babysitter

I am looking for a casual babysitter for when I go back to work, I will be working from home but will need someone to help look after my daughter. I will need help for 4 hours a day for 4 days per week alternating every second month. Days are flexible but time will need to be 9:30 - 1:30. Meals will be pre-made for my daughter, you will not need to do any cooking or cleaning.
