After School Nanny For 2 Children In Harpenden

Hello, I am searching for someone who can pick up our boys from school and watch them until we get home from work for a few days each week.
Ideally you'd help with homework, do projects with them and play.
They love Minecraft, dominos and circus tricks.
The school is a mile away, so ideally you'd be able to drive them, or perhaps cycle them if the weather is good.
