ungret help need for this writing and translation

i need help to write in Portugese a thesis report about astrophysics topic ( extended cosmological models ). I want a Latex format source.

WHAT I WOULD LIKE IS THAT WRITTER WRITES THE THESIS MANUSCRIT IN Portuguese AND AFTER, I WILL TRANSLATE MYSELF IT IN FRENCH.

BUT IF THE FREELANCER CAN WRITE DIRECTLY IN FRENCH, THIS IS EVEN BETTER.
