German speaker Childminder for a 5 yrs boy.

Hello

I have a 5 year old child who has been living in Germany during the last 6 months.I´d like he to keep on learning German, therefore now that we return to Spain,  I am looking for a German native speaker student who could pick my son up at school and bring him home, it wouldn´t be needed to stay more than 2 hours a day, and the number of weekdays to do that can be negotiated (2, 3, or 4)

Non Spanish speakers are welcome if you are able to speak English at least.

Salary to be negotiated.
