Looking for a babysitting job

My name is Jessica, I’m 22, and I’m looking for a babysitting job to do in the afternoons/evenings. Any day works well for me except Mondays and Wednesdays. 

I’m from the UK but I’m working in Madrid as un auxiliar de conversación at a high school with students aged 12-18. 

I speak British-English and can speak Spanish at a B1 level but can understand a lot more.
