Easy two days a week after school pick

We're a family of four and looking for someone to do school pick-ups on a Monday and Tuesday (3:00pm - 6:00pm). The school is walking distance from our house so a car isn't necessary but preferable. We have a son (7yrs old) and daughter (9yrs old) who are in grade 2 and grade 4. There will be occasional Friday or Saturday evening shifts as well as some days during the school holidays. Great kids who are easy to look after and love playing all sorts of games.
