Sitter in Acworth, Georgia

I am looking for a part-time sitter that has an open schedule and a car. I have a total of four kids, but the oldest is 15 and does not need to be watched and he goes to his dads on weekends and is in school during the week days. I also have a two-year-old boy that goes to school during the week days, but is home all day during the weekends. I also have two homeschooled daughters ages four and seven. I need a sitter to watch the kids while I have doctor appointments or errands to run, for me to get things done around the house, and date nights. I am also looking for someone to watch the kids for two weeks straight in the beginning of November during the day while I am recovering from surgery, date is not yet been set. Thank you for your time and consideration.
