Babysitter Needed For 2 Children In Jack London Square

We are looking for a great babysitter for 2 children in jack London square. One child is 3. 5 years old (girl, potty trained) and the other is 18 months old (boy, diapers). This would be our first time leaving the kids with a baby sitter. You would be responsible for giving them dinner (provided) and putting them to bed. We are also looking for someone that is also available to babysit the evening, roughly 4-9 pm, on Friday February 28th. We also have an old cat that will be hanging out.
