Shanez, offer part-time childcare in Bristol BS1

I am Shanez, the mother of Laszlo, 6 years old and Liv, a little girl of 3 years old who will start going to the same school as her brother next September: Hotwells Primary School (BS8).
I am currently looking for a person who can pick up Liv from school from Monday to Thursday from 3:20pm to 5:30pm. His brother, Laszlo, stays at the afterschool of his school and my companion picks him up every day around 5:15 pm. As I work from home, I need someone to take care of Liv outside of my home and drop her off around 5:15pm either at Hotwells Primary School or our home (BS1 5SY).
