Babysitter Needed for my Children - Full-time / Part-time

We need an after school nanny for our 2 children in La Grange, beginning in August. Duties include: letting our dog out, picking up our two children from school (both schools are walking distance from our home), getting homework started and watching them until we arrive home from work. Some light tidying up and potentially getting dinner started for the kids and/or our family would be part of our caregiver's responsibilities. Please be comfortable with pets. Someone who can help out with homework is a plus.
