After school childcare in Frankfurt

We are a family looking for an English speaking babysitter for our 2 children aged 2 and 6, Monday to Friday, from 4pm to 7pm.
We live in Westend Süd in Frankfurt.
The job consists mostly of picking up our 2 children at the French school (Lycee Francais Victor Hugo) in Rödelheim, bring them home in Westend Süd, bath them every other day, give them their dinner, get them ready for bed and play with them during extra time off course. Some simple cooking required occasionnaly. For the trip back home from school, metro is the easy solution ( U7, Stefan Heiser Straße -> Bockenheimerwarte).
Additionnal occasionnal babysitting in evenings possible, but only if babysitter is interested.
