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

We are visiting Hartford for the summer, approx. July 1 - Aug 15. We are renting a house that is walking distance to Main St. We have (4) children, ages 4, 3 and 7-mo-old twins that are not yet walking. We primarily need help with the twins, while the older children are at camp. Mom and Dad will be home, working from the basement while you care for the children upstairs. (Once per week, we may have you watch the older kids while the twins are at grandparents. Typically, you would not be with all 4 children, and if that was asked, there would be an increased hourly rate).
