English to German Translation Needed

I need an experienced translator to convert my document from English to German. The specific content topic is unknown, so a versatile skill set is required.

- You should have a strong understanding of both English and German.
- Any experience in legal, technical, or medical terminology would be a bonus.
- I expect the translation to be accurate, free of grammatical errors and retain the meaning and tone of the original text.
- Previous experience in document translation is highly preferred.

Your bid should include the amount of time it'd take you to complete this task. Thank you.
