Translate Health research questioner from Spanish language to English language

I am in need of a translation to a health research questionnaire from Spanish to English. The target audience for this questionnaire is healthcare professionals, so accuracy is crucial. I have not yet translated the questionnaire, so I need someone who is fluent in both languages to ensure that the translation is accurate and culturally appropriate. In addition to translation and validation, I also require proofreading services to ensure that the final product is error-free. Ideal skills and experience for this job include fluency in both Spanish and English, familiarity with healthcare terminology, and experience in translation and proofreading.
