Babysitter for our 14 month old daugher on weekends - father is Greek

We are looking for a casual arrangement with a Greek babysitter to look after our 14 month old daughter on some weekends. We may also need additional help in the evenings. We have a lot of space to play and a garden. We are also walking distance to Brockwell Park and Brixton tube station. The father is half Greek so would like the babysitter to speak greek to his daughter. There may also be an opportunity to provide house keeping and cooking services if this is an option but not a necessity. We look forward to welcoming you to our home.
