Sitter Job in Ridgefield, Washington

I have 2 kids, ages 6 and 12. You will spend at least 2 days a week visiting us, and the maximum time we will need you here is 2 hours to 2 1/2 hours. You don't have to come everyday; weekends off, but you need to be available 4 to 6 PM on weekdays. I will contact you when I'm running late and can't pick up my kids, so you don't have to be here all the time since some days I can get away early. You don't need to drive to their school, just wait for the bus to come in the afternoon. I would prefer at least 5 years of experience, although it's not neccessary.
