Looking For Early Morning And Late Evening Nanny

I am looking for a nanny Monday through Friday every other week. All children go to daycare so I will need someone that can come to the house early in the morning to get children ready for daycare and drop them off then picked up from daycare and fed dinner and ready for bed until we are home. my boyfriend and I work very early hours till very late sometimes. We do not have a set schedule so I need someone flexible I would like to just pay for the hours when you are with the kids. We do have 2 dogs so must be comfortable with pets. I will pay extra if willing to do some house keeping.
