Greetings, I'm a native Spanish speaker and expert English translators.
I have tools to do this FAST and clean. All I'd have to do is process the pdf, transform it to a .doc file and then check it for errors.
Of course, that would mean I'd take dramatically less time than writing it by hand, and the price would of course be lower too.
Rest assured the quality won't suffer at all from this procedure.
Warm regards,
Gabriel Jimenez
