Proofread Portuguese translation of PPC Adverts

I run a Google advertising company with several clients who require their ad copy in multiple languages.

This project is the first of many, and there may be an opportunity for continued partnership for the right candidate as and when we require further translation or proofreading services.

I am currently looking to have a set of adverts proofread and corrected. The adverts have been written in Portuguese, but as this is machine translation, I'd like someone to check them for general issues and grammatical errors.

The adverts have been broken down into individual sentences with a character count on Excel. This is due to us having a limit on how many letters can be used per line in the advert. I'd prefer to keep the excel format if possible.

You can see the scope of the project in the attached excel files.
