Translation of Extensive History Book to Spanish

I'm seeking a translator for a non-fiction history book with a word count exceeding 100,000. The book needs to be translated from English to Spanish, maintaining a formal and academic tone throughout.

Key requirements:
- Exceptional English to Spanish translation skills
- Experience with translating long-form non-fiction texts
- Ability to maintain a formal and academic tone
- Attention to detail and commitment to translating everything accurately

Please note, there's no need to keep any specific terms or phrases in English - everything should be translated. Ideal candidates would have a background in history or academia, but this is not a strict requirement.
