Dear Francot, I'm a native Portuguese speaker, I have a Master Degree in Languages, Literature and Cultures, and a vast experience as a creator of content (blogs, webpages, articles, articles with S.E.O. orientation, you name it). Being mandatory to be an impeccable proofreader too, I can give you unique content developed from your guidelines, in Portuguese, regarding proper punctuation, without any misspellings and syntax errors, and with correct grammar and adequate vocabulary. Please, check my private message for more details and work samples and see my blog at [login to view URL] for you to evaluate my writing skills. Thank you. Grateful, in advance, for your availability, Vítor Cortes
