Dear Sir or Madam,
I am writing to express interest in your project, for which I consider to be over-qualified. Let me tell you in short the reasons why I believe so.
I am an editor and writer of English and Spanish with experience in creative writing, editing and translation. I have undertaken jobs of a similar nature ever since I graduated with honors from University. I took part in the UN Language Competitive Examination, aimed at verifying the proficiency of thoroughly selected candidates across the globe. I also worked as a telephone interpreter for CTS Language Link and Day Translations, taking calls through Skype.
Furthermore, I worked as a telephone interpreter in the same pair of languages. My primary focus in on English, as I took specialized courses in editing and writing as part of my continuous education. Hence, my qualifications excel the nature of the task itself, which could be performed at once provided your approval.
At present, I am in need of a long-term job. Recently I moved to Europe and my current situation is rather unstable. I will commit to a responsible and serious employer who can take advantage of my work provided we can agree upon terms of working conditions, such as deadlines and fees.
