Afternoon Sitter Needed To Help With Pickup, Homework, Dinner Prep

We are looking for a fun, patient, experienced babysitter who is looking for afternoon/evening work for our 11-year-old son. He is very funny and sweet but he needs someone who can pick him up from school, keep him on track with his homework, do quick dinner prep (we get a food delivery service so everything is already measured out and is very quick to cook based on a recipe card), and then make sure he gets to bed on time. Both my husband and I work full-time so we need someone who is very reliable and able to do things independently without a lot of oversight. We have had great experience with sitters in the past who have been actors or in school. We would prefer someone who could help out with light housekeeping and homework help. We would prefer a babysitter who does not smoke and who has college degree.
