Hi. I can help with your research. I´m an American writer, editor, researcher and translator, a native English speaker living in Brazil for the last 30 years (after having lived and traveled in Peru, Colombia, Venezuela, Bolivia and Argentina), with excellent language skills and years of experience. I´m fluent in English, Portuguese and Spanish. I would like more details about what you need so I can define the scope, cost estimate and delivery date for your project. Please contact me for further discussion. Thanks, David
