Looking For Afternoon/Early Evening Help With Two Great Kids!

We are looking for help with our two awesome kids, who are very mature and smart and self-sufficient but have lots of afternoon activities plus parents who are traveling a lot for work! The ideal person can help the 8-year-old with homework, feels comfortable driving the kids to activities, and when the kids are set, can just be an extra pair of hands for things like picking up groceries, and helping us to prep dinner or keep the house tidy. There might be occasional overnights. We also have two very sweet cats who don't seem to bother the allergies of our older kid. We've done really well with smart, fun people looking for a stable part-time source of income while they pursue their dreams. We're happy to provide references from our previous babysitters.
