Babysitter Needed

My husband and I are looking for a babysitter who would be available Mondays, Wednesdays and possibly some Fridays to assist with child pick up and babysitting while we are at work. We would not need someone every week each day, and would provide advance notice! Times would vary, but be within 7:30am-4:15 p.m. or 2:00pm-5:30 p.m. time frames. We currently have a nanny who covers our Tuesdays and Thursdays and some Fridays, so we are looking for another to add to our rotation! We would provide the mode for transportation if our children needed to be picked up.
