Part-time care needed.

I am looking for some help with my three primary school-aged children. We will need someone to pick up the kids 1-3 days per week from school and stay with them at the house for about 2-3 hours. During this time, all that will be required is help with homework, preparing them an afterschool snack and any other smaller duties that may be left, like emptying the dishwasher, assisting the kids with emptying their backpacks, and keeping the kitchen area clean. We also have a dog, so being comfortable with her is a must as well :) (Part-Time, Live-Out) For day, evening
