Hello,
I'm French native ( in fact I'm also bilingual French-Portuguese).
I can proofread and/or translate accurately your text.
In order to give you a real price and timeframe for the job, I would like to see the doc spreadsheet, or I will need to know how many words it has, and what kind of text it is (general content, technical...) .
In all cases, I would ask for escrow deposit of 100% before starting the job.
Thank you for your attention.
At your disposal,
Miguel
