Dear lindauradasilva, I have a Master Degree in Languages, Literature and Cultures, and a vast experience as a translator (websites, legal and technical documents, articles, eBooks, books, you name it). Being mandatory to be an impeccable proofreader too, I can give you a flawless translation of your book (80 pages), regarding proper punctuation, without any misspellings and syntax errors, and with correct grammar and adequate vocabulary, from Portuguese into English (US). Please, see my private message for more details and work samples. Thank you. Grateful in advance for your availability, Vítor Cortes
