I need a Spanish translator for a research document

I am looking for a Spanish translator who can help me with a research document. The document is more than 20 pages long and I would prefer it to be translated into Latin American Spanish. Additionally, I would like the translator to proofread the document after translation.

Skills and experience needed:
- Native or fluent in Spanish
- Proficient in both written and spoken Latin American Spanish
- Experience in translating lengthy documents
- Attention to detail for proofreading the translated document
