bonsoir svpp quelqu'un pourait enrichir/améliorer mon texte. Merci

Dear Sir or Madam,

I am writing to you because I need to find a job to finance my studies .
I am 14 years old and a student at Elsa Triolet college in Lyon. I am very interested in this job because I love take orders and serve costumers in a restaurant. I haven't got experience in this domain so It is a rewarding experience .
I enjoy being in contact with the costumers and I work very hard so I think I would be brillant for the job.
Thank you for your attention.
Sincerely,
