Experienced After Nursery Nanny And Occasional Weekend Afternoon And Evening Babysitting

My husband and I are from South Africa and looking for someone to help out twice a week to pick our 2-year-old daughter up from nursery as I work in the office Mondays and Thursdays and get home quite late.
We don't have any help or family here so having someone free on weekends once or twice a month would be a bonus.
