Native English speaking student for language practice

We are looking for an English speaking student to help our 12-year-old daughter improving her language skills. She is nearly bilingual, so we just want someone to speak with her a few hours per week. We have hosted several au pair students over the last years, so the interaction with our daughter and with us should be easy. We live in Oviedo, at  a 20-min walk from the Campus del Milan.
