Looking for a babysitter for my daughter

I am looking for someone to help me with my daughter 4 days a week, Monday-Thursday 16:30-18:30 more or less. The job would consist of of picking her up from school and staying with her until I am done with work. It would also consist of helping her with math work, reading and writing. We are based in Somosaguas which is a short bus ride from Moncloa. I am looking for someone with a teaching experience.
