Looking for a babysitter to help with 2 children aged pre-school and infant.

For my oldest (almost 5yo), I need help with the following:
Wednesdays (4 hrs):
- Pick up from school at 11:30AM
- Have lunch with her at the school cafeteria (11:35-12PM)
- Play with her (12-3:30PM); can be a playground or at home
Fridays (1.5 hrs):
- Play with her from 10-11AM
- Take to school at 11AM and have lunch with her at the school cafeteria (11:10-11:25AM). Then walking her to class at 11:30AM.

Additional help needed occasionally:
- Picking up groceries, filling up gas in the car,
- A few hours on the weekend (likely a Saturday) so we can have a date night; would need help with both kids (1yo and 5yo).
