Dear Sir,

I'm very excited and delighted over the good news that you are recruiting an administrative assistant. From the enclosed resume, you can see that I once worked in a famous multinational corporation for three years. I am very skilled at dealing with routine office work, and my major in college was office automation systems. So it should be clear that I am qualified for the job.
With respect to salary, my requirement is four thousand dollars one month. I assure you that if appointed, I will do my best to meet or exceed your expectations.
I hope I may be granted an interview, so I can fully explain my qualifications.
Looking forward to hearing from you soon.

Sincerely yours,
Lulala Yea
