Nanny Needed For My Children - Full-time / Part-time

I'm a hair dresser and my husband is a paramedic so our schedules will vary week by week, thinking about 54 hours a week give or take a bit. some days will be 630am-730ish pm and other days 12-730 p.m. we are desperate for someone to help out, we're going through a divorce right now and can only offer $300/week.
