Babysitter Needed Fridays After School In December

My son is 6 years old and needs a babysitter after school on Fridays. He's a special Ed kid with a learning disability, so his language skills and interests are closer to that of a 2-year-old. He enjoys walks and playing at the playground. It would be nice to have a sitter with experience working with a special needs kid, but anyone with ample patience and kindness would be fine. He goes to school and will need to be picked up there either with a car or with the bus (he loves the bus). We'll provide for the cost of some after school activities, such as going to the zoo or Discovery Center.
