Dear Sir or Madam,
I would like to submit this proposal for copywriting in Czech. I am a native Czech speaker with bilingual English and quite rich experience in translation and writing on a variety of topics. I have done copywriting jobs for several projects in the past where I mostly wrote texts for commercial websites and social media. I left the finishing deadline on 7 days since you do not mention how long would the cooperation be. Therefore, we can discuss the deadline(s) further to your satisfaction. If it would be helpful to you, I can provide an English proficiency certificate and some examples of my work in English (or Czech if desired).
I would love to hear more about the project and what kind of texts you require. However, I am confident that I can provide you with high quality texts quickly.
I am excited at the prospect of working with you and hope to hear from you soon.
Best regards,
Lucie Kulhankova
