Hi!
As a Brazilian Teenager growing up at a point where TV shows would take so long to be on air here, I ended up being part of a team that would make the subtitles for free for other teenagers like us. Besides on tv shows, I also did the same job with interviews, and longer pieces.
My big experience in this field is as being a teenager fangirl, but now, at 25 -and still a fangirl, I'm sure that I can help you with transcribing and timing your videos or translating your documents.
I'll wait for your contact.
