Nanny Needed - Full-time / Part-time

We're looking for someone to pick up our son from the bus and hang out with him until we get home from work. We haven't yet arranged any after school activities, so it's possible we may need you to help get him to/from things - ideally on the subway or bus. (If you happen to have a car or a cargo bike, let us know, but that's not required.) Our son is a lot of fun. Very curious and funny. He's not particularly athletic, but he likes riding his bike. He's into Pokemon cards, rocks, crystals, and gems and likes to start an art project, but doesn't always finish it.
