Babysitter Needed for my Children

We have three rambunctious children. Two, almost 7-year-old boys and an almost 3-year girl. The boys have been home for the summer and we are looking for someone to get them a bit more active during the day, a few days a week. We are also interested in someone who could do some afternoons/evenings with all 3 children so my husband and I can have a few date nights. We are also hoping this person will be interested in continuing on during the school year a few evenings a week and some weekends.
