Hi, I'm Fabian and I'm a native Spanish speaker. I'm a Spanish-english/English-spanish translator and as a freelancer I also do transcriptions, subtitling and online language tutoring.
I've worked in similar projects before, along with other other translators, subtitling and translating different types of documents, over one million words.
If you're interested I can send you the link to my portfolio so you can see some samples of my previous work.
Also, I think it could be a good idea for both of us, to first send me a sample of what I would be working with, just to be sure I deliver something that meets your expectations.
