Blog Commenting - I'll supply the blogs

I need someone who can comment on blog posts in a meaningful way. I will supply a list of blog posts, urls and keywords. The task will be to read the blog post and make a comment that will be approved by the blogger using the supplied url and keyword. The comment should contribute to the blog. No "great blog" type posts. They will get rejected. You will provide me with a spreadsheet of urls that you have placed comments on. I will pay per approved comment. I can verify the comments were approved or you can do it before you send them to me, either way I will verify again. Please provide a per comment bid for a batch of 100 comments. I will award project based on your ability to demonstrate previous quality work, with price as a second factor.
