Preschool teacher for one child, 10 years old, Athens (center)

We live in Filothei and are looking for a child minder, preferably with pre-school/nursery experience to look after our 4 year old daughter. Primarily this person will play creatively in Greek with her in order to encourage her Greek language skills. We would like this person to start immediately during after school hours (3pm-7pm) and then during the summer holidays all day (10am-6pm) during July and part of August.
