Nanny/On-Call Babysitter Needed For 3 Children In Grass Valley

I'm looking for a great babysitter that has lots of flexibility for 3 children. I work an on-call work schedule and each day varies. I definitely need two full days a week as well as someone to be on-call for me. Usually the earliest I would need someone is 6 a.m. and the end time will vary depending on when I can get home or when my husband can get home from work. I need someone who has a reliable car and can take my children to and from school as well as after school actives if needed. Light housework is highly appreciated as well as help with homework and food preparation. Basically, I need another ME! I would love if I found someone that doesn't have their own children or that is older and is looking for three really sweet kids to be around. We have one very big friendly dog who roams around the property and mostly minds his business.
