Personal Letter Translation: Spanish to English

I'm looking for a proficient translator to convert a personal letter from Castilian Spanish to English. The primary purpose of the letter is personal, and it contains some medical terminologies. Here's what I expect from the ideal candidate:

- Must have fluency in both Castilian Spanish and English. Familiarity with the cultural nuances of these languages is a plus.
- A strong understanding of medical terms is vital, as the document contains some technical medical terms.
- Demonstrable experience in translating personal letters. Past work samples would be appreciated.
- Maintaining confidentiality is crucial as this is a personal document. The translator must adhere to a strict privacy and confidentiality agreement.
- Attention to detail and ability to respect the original content's tone and style is vital.

This is a one-off project, but if the chosen candidate performs well, they could be considered for future opportunities. I'm excited to see your proposal and discuss the project further!
