Spanish nanny

I am seeking a job as a nanny/babysitter. I am a 26-year-old Spanish girl and have just finished my degree in university and I have come to London to work and improve my English.
I have experience looking after children of all ages, above all from my family. For references, I have some telephone numbers in Spain to which you can call (they just speak Spanish), but I have a translated letter.
Before, I come to London I was looking after two children (ages 4 and 7 moths), I was taking the 4-year-old girl to school and to her after-school activities, bringing her home for lunch and playing stimulating and enjoyable games with them.
I love children and would like to work as a nanny in London. I have intermediate English level. I also have experience in housekeeping and cleaning. I am very conciencious with cleaning. Your home will always be tidy and clean.
I can also teach Spanish to your children and speak Spanish with them.
I am also available to do any babysitter in the evenings if your require.
If you need any further details please do not hesitate to contact me.
I am looking forward to hearing from you.
Thank you very much in advance,
Cristina Hernández.
