Dear Sir/Madam,
I would gladly work for you, and I believe that I am perfectly fit for such a project, because I am highly experienced in both English and German.
First of all, I have been studying English and German for more than 10 years and I enjoy writing any kind of articles/stories. I can write about anything you desire. I am certain that I would be able to do a great work if you chose me, as I am an ambitious and serious person.
If you wanted, you could ask me for an article, and I could write it on the spot, so you could decide whether you are fond of my writing style or not.
Thank you in advance,
Yours faithfully,
Mihnea Melencu
