Babysitter Needed for my Children

I am looking for childcare primarily for 2 children ages 5 and 2, 2- 3 days a week (preferably Mon-Wed). The 5-year-old will be in a preschool program from 12:00-2:15. Pick-up/drop off capability would allow for additional hours to the right candidate. I have a 6-year-old son who is entering 1st grade. Depending on pick-up/drop off capability and agreed upon hours he may be in the mix for 1-2 hours in the afternoon. I am flexible with days/hours for the right candidate. I work from home and would be accessible if needed.
