Blog posts

I own blogsites and I am looking for a well experienced freelancer who can provide consistent postings. These blogs are for 3 separate niches (health, finance and lifestyle). I am aiming to ultimately get affiliates and generate more sales.
Each posts should be 750-1000 words. I need 2 posts per site so a total of 6 blog posts in a week.

This is for an on-going engagement.
