Dear Sir or Madame,
I am a recent University graduate with professional skill in academic writing. I currently have access to several university libraries (online) and would be able to complete your request with great satisfaction.
I would be willing to write your blog post on the first four subjects. I will take 2-3 days for research and would then start a draft for the articles. Once the drafts are done, I will get in touch with you and you can decide whether you want to see and amend them, or if you want to see the final result only.
If the above sparks your interest, feel free to contact me.
With kind regards,
Michael Wienhold
