Regular babysitting 5 hrs/week

Hi!

We are looking for a regular babysitter for our 6 year-old daughter and 2,5 year-old son starting September.

On Tuesday, this person would be in charge of picking up our daughter at school, bringing her to her plastic art lesson, making her snack on the way, and then picking up our son at his regular nanny's place and bringing him home and of course playing and chatting with him. He likes to ride bike in the park, and play ball but also coloring and drawing.

The second day can be chosen among Monday, Thursday or Friday. It would consist in picking up our daughter at school, making her snack and of course chatting and playing with her in English. She likes handcrafting, painting, card playing but also biking or having fun in the park.

Pick-up time at school is 4:30PM, so we need someone really punctual.
We want someone who can commit at least till the end of the school year.
Technically, even if the job concerns two children, the babysitter would care of only one child at a time.
We hope this person to be dynamic, enthusiastic, able of offering ideas of games or activities, sweet, patient, at ease with girls and boys, and especially with little ones.
References would be appreciated.

15€ net / hours (position will be declared) 5 hours a week (excluding school holidays).

We live nearby Paris 2-minutes walk from the subway station "Mairie d'Ivry" line 7, and 15 minute-walk from the RER C station "Ivry-sur-Seine". 
Everything (activities, school, nanny) is in a walking distance.

Only survival french is required.

Don't hesitate to contact me for any further information.
