Care Needed For 14 Year Old Twins In Olympia

We are looking for a part time nanny for 2 children (twins age 14, boy and girl). Duties would be Monday to Thursday and include light housework. Help picking up kids Monday-Thursday from school at 3:40 p.m. (M, T, Th) and 2:40 (W) would be required and taking to tutor on Monday and Thursday (5:30) and occasionally to soccer in the evening. More hours needed on weeks when one parent is traveling for work. Otherwise flexible on hours, but would be about 10 hours per week. When school finishes in June we would need some, but less care but could guarantee some hours and then back to a school schedule in September.
