Nanny Needed

We are looking for someone to get our 7-year-old daughter off the school bus on Wednesday's at 315 p.m. and hanging out with her till we get home from work around 530 p.m. We are also hoping this person would be interested in helping out on occasional date nights and school holidays/half days. We do have a 4-year-old daughter as well, but she is in full day preschool and would only need care on date nights. Must be ok with dogs, we have a big friendly black lab!
