When I was a teacher years ago this was the perfect after school gig! I got paid 200 weekly for like 4 - 5 hours of work. It was also under the table. I don't know that it would have been worth it to me to take that job with taxes taken out. Just being honest.

You don't want a nanny; you are looking for a regular babysitter. I would vote for going on Next Door or a neighborhood/town fb page.
