To whom it concerns:
I would be happy to create content for you on almost any topic, provided that you give me some clear instruction as to what you want.
I am a native English speaker; I have a clear grasp of grammar, spelling and syntax, as well as a flair for writing. I can create compelling, interesting articles for you or clear, factual ones, depending on your requirements.
If you could let me know what you want, exactly, I will be happy to begin work on creating the content as soon as possible.
If you have any questions, please do not hesitate to contact me. I look forward to working with you.
Kind regards,
R. Miller
