Hi. Being a lifelong student of EVERYTHING at the age of 64, I was interested in what you want written about this subject. Although I live in Brazil now, I´m an American researcher, writer and editor, a native English speaker with excellent language skills and years of experience at producing and improving texts of all kinds. My basic rate is $10/1000 words, which I can lower if the work is not urgent or if the volume of work is large. Please send me more details about your project, I´d like very much to work on this with you. Best, David
