Part-Time Nanny

We are looking for a part-time nanny that would work 8-5 Tues-Wed and possibly additional days depending on our work schedule. My wife works part-time, and I own my own business so the hours would vary week to week. We need someone who is flexible with hours along with an impressive background and reliable. If you cannot show up to work on time, you will not be employed with us for long. We are looking for someone who wants to be with a family more than a year.
