Article Writers Needed (Brazilian Portguese)

Hi there, I am looking for someone who can write articles in Brazilian Portuguese about male and female fitness and bodybuilding. I will need a total of 30 original articles, each around 500 words long on provided topics. They will also need to be keyword optimized for SEO (feature the chosen keyword a certain number of times etc). You must be a fluent Brazilan Portuguese speaker/writer who can write articles to a high standard. Please bid for a package of 30 x 500 word articles. Thanks.
