Spain, Argentina, Colombia, Venezuela, Panama. Peru, Mexico, native espanol

I'm looking to hire someone who is proficient in Castilian Spanish to produce content for my project. The content needs to be a translation of more than 1200 words. This project will focus on Spanish-speaking countries like Spain, Argentina, Colombia, Venezuela, Panama, Peru, and Mexico so a native speaker of the language is preferred. Accuracy is important and the candidate must have a good understanding of the language and its nuances. If you possess the skills and knowledge necessary for this project, I'm eager to hear from you.
