Dear Sir,
Having heard that the situation of a cashier in your office is vacant. I wish to offer my services for it.
I am 22 years of age, and have worked for twelve months in a similar position for New World Trading Co.,Ltd., to whom I can refer you as to my character and ability. l left them solely because they made a reduction in their establishment.
Regarding salary, I leave that with you, but feel certain that I can earn at least 2,500 dollars per month.
I hope to have the pleasure of your granting me an interview.
Very truly yours,
