Dear Mr.Williams， Your advertisement in this morning’s paper for manager of public rela

Dear Mr.Williams，

Your advertisement in this morning’s paper for manager of public relations appeals to me.I found the wording of your advertisement quite attractive with emphasis on leadership，initiative，and flexibility.And my experience and qualifications indicate that I am the person you are seeking.

The enclosed resume indicates my experience in the area of public relations and management communications. I am quite familiar with the kinds of issues and problems that you have to deal with.

I’d like to draw your attention to page 2 of my resume，on which I describe my concept of public relations. And I am most eager to put this concept into practice to prove it to you.

Although I have been very happy with my present employer and colleagues，I am more willing to join your company where I can assume even broader responsibility.

I am free to travel and open to relocation.I would welcome the opportunity to meet you and to further discuss how I may benefit your organization.Please call me at 0411—89726374 to arrange an interview at your earliest convenience.

Sincerely yours,

Stephen Smith
