Dear Sir or Madam,
I would like to offer my services to you. I could offer you 25 $ per 100 words for this collaboration.
I am a native German with an excellent knowledge of the English language as I spent several months in English speaking countries. Thus, my understanding of the source text, both German or English, is excellent which is essential to be able to provide high quality translations.
I have been working for companies before where I was responsible for translating also the correspondence and answering letters in both languages. I have studied to become a foreign language correspondence clerk. Thus, I am very familiar with the common ways of writing in business. Furthermore, I have a translation degree and a business management degree.
In case you have any further questions, please feel free to contact me at any time. I will also send my CV for further references if requested.
I hope to hear from you soon.
