I am a freelancer, and have translated over 250.000 words successfully. I have both the experience and tools to give you the best possible translation:
Writing: I have a solid use of grammar and syntax;
Localization: I'm able to transfer the cultural context from English to Portuguese, and vice versa;
Transcreation: Capable of capturing the original intent, tone and context.
Your translation will have quality: won't be something out of Google Translator.
All professionally done.
