Proofread and Translate Documents.

I have a text (5000 words) translated by an Automatic Translator then proofread. This document is supposed to be for a submit application which was rejected, because they could spot the difference between an Automatic Translator Device and a hand made typed Spanish translations write-up done by a local Portuguese speaker and translator. I need someone whose native language is Portuguese to proofread it and fix any errors which might include: bad grammar, wrong sentences, misused clauses, prefix, phrases, verbs, nouns and so on (wrong word used), wrong position of words, sentences that don't make sense etc. The goal is that the final text (after editing) looks like it was written by a Native Portuguese. There's no need to report each bug or highlight the changes you've made - just make the changes and re-upload the file after you've done your part. I can easily see what changes have been made. I may have more than 1000 of these ready to finish because it's an organization paperwork submit for a mutual agreement/collaboration with several partnering companies in Brazil.
