Looking for a native English-speaking nanny for our 7mo baby

We are looking for a native English-speaking nanny for our 7month old baby. Working hours will be Monday to Friday 9am to 4pm approx., although still TBD. Previous experience is a must and relevant education is preferred. We need someone who is available at least until February, although if we find the right person who is also happy to stay longer, we might extend the contract (VISA required!) until the end of the school term, or even into the summer. We would prefer someone who can cook (basic meals) and is happy to do a bit of housekeeping. Ideally, you will be a student or recent graduate, with child-care experience, a passion for education, a non-smoker, open-minded, sensible and easy-going. We both speak English so it's OK if you don't speak Spanish - but of course we're happy to help you out if you're learning the language. Looking forward to meeting you soon. (Please note we are only interested if you are currently living in Madrid and are a native English speaker).
