Nanny Needed For 1 Child

We are looking for a great nanny to take care of our son, M, two days a week! I work full time from home, but still need someone to take care of him while I am working. This would be guaranteed to be two days a week to start but could expand to three days a week (we are figuring out what we need as we go!). Additionally, my husband is a musician who tours, so there may be weeks with the option to be full time, but that would be planned in advance. We would prefer a nanny who has their own car, who does not smoke and who is comfortable with pets (we have two cats!). We dont need much in the way of cooking or cleaning - just watching, feeding, playing with, and engaging the little guy! I would also love for this to be a long term gig as we will need ongoing support for several years.
