Native Portuguese or Brazilian writer requested

Hello,
I am searching for a native Portuguese or Brazilian writer who is Christian/Catholic to write a religious article.
My client is an Catholic eCommerce site and for guest posting I will need someone who can write in Portuguese. The article will be placed on a Brazilian site, hence I am looking for native Portuguese from Brazil would be even better.
Translating to Portuguese is not good enough, you MUST be a native Portuguese speaker or better writer.
