Baby-sitter for 2 years baby

Hello,
I am looking for a nanny to take care of my two-year-old son during our stay in Greece, Anavissos - Sounio. We will be there from July 28th to August 1st, and I will need your services on the following dates:

July 29th: mainly in the evening, as we will be going out for a birthday celebration.
July 30th: from 10 AM to 4 PM.
July 31st: from 10 to 4pm
I am looking for a trustworthy nanny, neither too young nor too old, who is energetic and able to keep up with a two-year-old. It is essential that she has experience with young children.

Thank you in advance for your help.
