Babysitter Needed for my Children - Full-time / Part-time

We're looking for a caring babysitter/nanny to help with our two young girls in Scituate. Looking to have a set schedule with two days a week, 4 hours per day (W/F or M/W preferred), plus occasional weekend/date nights. Additional hours will likely be available on a week to week basis, if interested. We have a friendly dog too - so must be comfortable with pets!
