Hello,
I have several years of journalistic experience and a B.A. in English Language and Literature, which, I believe, make me qualified for this job. I do not have a significant portfolio, but it is, to a certain measure, a testimony of my skills, at least in the domain of nonfiction writing.
Apart from that, I can guarantee you that I am professional, dedicated and affordable employee.
Thank you for taking time to read my proposal, and I hope to hear from you soon.
Kind regards.
