Part Time Nanny (Afternoon To Early Evening) Needed

My wife and I are looking for a part time nanny to help with our two children (a girl age 12 and a boy age 14). This would be to mostly help with school pickups as well as getting them to other afternoon activities and possibly a little bit of homework help (mostly for our 12 yo). We do have two dogs and a cat, so being OK with animals is a must. Ideally this would be 5 days a week, but can be less if that is ultimately what works. In a perfect world some light housekeeping (really laundry and help with changing sheets) would be part of the job description. Our daughter is a delightful outgoing person who loves arts and crafts as well as horseback riding. Our son is a bit of a bookworm who loves to swim and play video games. Both are involved in extracurriculars and help is certainly needed in moving them to their activities.
