Childcare Needed

My wife and I are looking for a nanny who can help us out during the week while my wife does homeschool lessons with our children. A 4 and 5-year-old who do kindergarten lessons together and a 3-year-old who does separate preschool lessons. It would be watching the ones who arent being homeschooled. We have a 1-year-old who would need to be watched the entire time but it would alternate between the other 3. The hours would be 9 to 2, 4 days a week; Monday/Tuesday and Thursday/Friday. This would be every week until next summer starts.
