Part Time Summer Nanny For 6 Yr Old Twin Girls

We are looking for a great nanny/babysitter for 6-year-old twin girls in Omaha. Schedule would be part time, and may vary each week according to our work schedule. Maximum hours would be 7:30 a.m. -5:30 p.m. Wednesday, Thursday, and Friday. We may be flexible with available days, but maximum availability would need to be three days a week. We would prefer someone who could help out with light housekeeping. We would also require a nanny who has their own car, and is comfortable transporting the girls and planning activities outside of the house as well as doing reading and writing activities. We do have two cats, and live in northwest Omaha near 144th and Fort. Nanny will need to be CPR trained. Possibility that nanny could extend to before/after school care when summer is over.
