Hi Dantaspaixao,
my name is Michael, i have been professionally writing for the last 3 years. My rates normally start at $0.05 per word, however, considering this is regular work i have dropped my pricing to below $0.03 per word.
You can hire some crappy writer for peanuts but you won't get quality work. So if you do want quality, you know who to choose.
I hope this is the beginning of a profitable long term business relationship.
Best wishes,
-Michael
