Afterschool Pickup And Care Needed For 2 Kids (6 And Almost 4)

We are looking for a fun, reliable babysitter to watch our two kids weekdays after school. Responsibilities would include pickup of youngest child from school ( 1 mile from home with the use of our car) at 1:30. Pickup older child from bus stop at the end of the street at 3:30. Play with children at home until 4:30. We would also like someone who can come in an hr earlier to do some light cleaning and pickup of the house. Must be able to swim and have CPR certification (we are willing to pay for certification if needed). We have 2 cats but you will not be expected to care for them.
