Childcare Needed

I'm looking for a regular, reliable babysitter for 2 kids (ages 9 and 11) involving school pick up (we provide car) and after-school help (homework, getting them ready for activities/sports, laundry). It's Tuesday and Wednesdays but opportunity for additional hours (date night sitting, days off from school, etc,). Must have experience and patience with siblings close in age and the bickering that often accompanies that! We also have a friendly dog - no work required there! We are located in the Italian Market area and the kids' school is about 8 blocks away. We provide a car for pick-up. $22 p/h.
