Freelance writer

Dear Ms. Sir,
Thanks for the beautiful spread you gave me in your recent issue. I'm glad the piece worked out for you.
Mark Kennedy said you might be looking for a freelance editor to make regular contributions to your Earth Science section. If so, I'd love a chance at the job.
Although you know my work, I've enclosed a copy of my resume so you'll have a better idea of my overall background. I know I'd do a great job for you and would love working with you and the other staff on a regular basis.
I'm looking forward to hearing from you.
Sincerely,
