Current College Students - After-School Babysitter in Arlington Starting Late Au

We are looking for an after-school babysitter for our son who will start kindergarten at the end of August. We are looking for at least 4 days a week, from around 3:30-5:30, although that is flexible as he will be off the bus around 4. Responsibilities will include picking him up at the bus stop around the corner and spending time with him at home or the playground near our house. Typically at least one parent will be home working during this time. We also have a toddler who may occasionally be home - we will pay extra for those days - and there is potential for night/weekend sitting jobs as well. We also have a small, friendly, hypoallergenic dog. Our house is a 20 minute walk from Ballston metro. $17-$19/hour.
