Short Term Help Needing With Carpooling And Supervising Dec 9-Dec 13

I need help short term with a 4yo and a 7yo. The most crucial times are Mon December 9 - Friday Dec 13. from 3:00 p.m. to 6 or 7 p.m. depending on availability. An extra hour from 8:15-8:50 for morning drop offs would be ideal if feasible, as would a 3-4 hour slot on Sunday December 8th. Duties include carpooling to/from school, after school routines, supervision of homework, age-appropriate activities/outdoor play, supervising childrens dinner and/or help with bedtime routines depending on the nanny's available hours. Must be reliable, have own car and be a nonsmoker. If interested Thanks, Roxanne
