Seeking babysitter/home help, okay with irregular schedule & ~10 hrs/wk

We are looking for someone who is comfortable with varied responsibilities and an irregular schedule. Kids are 3.5, 7, 10. Kids are homeschooled and kid-based responsibilities may be helping with "homework", keeping the 3.5 y.o. entertained. Non-kid activities may be preparing snacks or lunch, kid laundry, light housekeeping (meal clean up, assisting kids with tidying, empty dishwasher). Hours would be irregular - we would discuss as-needed the upcoming schedule for the week or month. Looking for someone flexible and up for chaos! :)
