Babysitter wanted for childcare in Calgary

Our family is fairly new to Calgary, just moved this summer. We're looking for a reliable and fun sitter for our 8yo son for occasional evenings and potential after-school care (occasional, not regular). He goes to public school in Glenbrook, currently in grade 3. He's super into reading, Lego, Minecraft, anything robotics, ninjas, superheroes, skiing, martial arts, all the fun stuff. He's smart and imaginative and well-behaved.
