Bilingual Translator: Spanish & English Needed

I'm in need of a proficient bilingual translator who can fluently translate documents from English to Spanish and vice versa. The scope of the translation job involves:

- Different document types such as legal, technical, medical, books, miscellaneous documents, and newspapers.
- The translations performed should not be straightforward but involve transcreation. In other words, re-creating the original text considering the cultural context.
- The output of translated documents should be delivered in Word format.

The ideal candidate for this project should be detail-oriented, possess strong understanding of both languages' nuances, and have prior experience in transcreating content. Familiarity with legal, technical, and medical terminologies is highly desirable.
