Babysitter Needed for my Children

My kids come home from school around noon. I am looking for a nanny / babysitter to watch the three kids until dinner time when I am off work. I work from home and my wife is on bedrest so we will be home and upstairs but need help with our children in the afternoons. We can be flexible on which days you can work and start and stop time but we generally need consistent weekday childcare from approximately 1 - 6 p.m.
