Formal Letter

Dear Sir:
Hello my name is Tom Pratt and I am sending you this letter because I want the job of waiter in your "La Nueva" restaurant. I studied in the International University of Mendoza, then I graduated and got my first job in a Sushi's restaurant.
I worked in many other restaurants as a waiter, chef and also as a cashier and I am very good in all those things. The best restaurant where I worked is called "La Florencia" and is the best restaurant in Buenos Aires.
I hope you accept me because I like restaurants very much.
                          Regards,
                                         Pratt.
