Overnight Babysitting For 2 Child In Brea

I'm looking for part time overnight babysitting in Brea starting around 8 p.m. Saturday night, through Sunday Mornings around 11 a.m. Sundays I would like to you to take them to their Christian Church within walking distance. They are good kids and the 11-year-old is essentially 16 right now but they are very bonded and attached to each other and well behaved. We are divorced and this opening would not be every weekend, only 1-2 Saturdays and 1-2 Tuesdays per month with Tuesdays requiring taking the kids to school on Wednesday morning. Saturday hours would vary between 8 p.m. (Sat) - 11:30 a.m. (Sun) Tuesday hours would be 7 p.m. (Tue) - 8 a.m. (Wed) with driving 25 minutes to school for drop off Wednesday morning.
