Babysitter/Au Pair

I am a student from Scotland, currently studying Law in Getafe. I finish University here in May, however I would like to stay until the end of July. For this reason, I am looking for a job as a babysitter or as an au pair for a family who want to help teach their children English. I would also really like to improve my Spanish to as high a level as possible. I love working with children and have some experience babysitting for my neighbour's children at home in Scotland. I already have accommodation so I would not need to live with the family.
