Chelsea, home help in London SW1X

Dear whomever this may concern
I am a 16 year old ballet dancer moving to England to study at a ballet school. As rent is very expensive, I am looking for a job like this to help me raise money for my school fees and give me somewhere to stay.
Unfotunately, I may not meet all your requirements but I am responsible and mature and I am willing to learn any new skills that would better equip me for the job.
I have lived alone for 6 months and I am capable of housekeeping, cleaning and cooking as well as looking after children and pets and caring for the elderly
I currently work as a waitress in South Africa, but a job like the one you are offering would suit me perfectly.
I hope to hear from you.
Many thanks for your time :)
Chelsea
