After school care for two kids

Hello! My name is Cass and my husband and I are looking for a nanny/babysitter for Mondays for our two kids (5 and 7 year old) for after school care (3-6pm). Ideally this would involve collecting the kids from school, serving afternoon tea, playing and doing activities with them (and cleaning up afterwards) and bathing them. If things go well, we may extend our days to include Tuesdays and request ad-hoc evenings.
