After-school Nanny

Looking for someone to pick up 2 kids (8 and 6yo boys) from school and drive them to activities and/or home and give them dinner. Pickup is at 3:45, and approximate end time is 5:30. We live in Woodbury, school is in St. Paul Park, activities are in Woodbury. We can either have someone every day for set/guaranteed hours, or go week by week, since there are some days when I can pick them up (my schedule is variable). We have a 10-month-old puppy who would not be your primary responsibility, but she might be around and might need to be let out sometimes.
