Before School or After School Work

I'm looking for help on a somewhat consistent basis for after school pick ups, homework help, dinner, and bedtime. There are times where you may not be needed some days and other days where you will be needed through late nights. I'm hoping for someone who has the afternoon/evening flexibility for this type of schedule. M-F 3 p.m. - 8 p.m. some days, 3 p.m. - 11:30 p.m. other days. And a mix in between! Fluent in both English and French is a bonus but not required as we are a bilingual household.
