Blog commenting and chat forum commenting - link building

I am looking for a VA to assist me with the promotion of my website (specialty cars) by posting comments in various blogs and chat forums. List of blogs and forums will be provided. I would like each post to be 50 words (minimum) in length, thoughtfully written providing value to the other webmaster. In other words, the post needs to be intelligent, and obvious that the blog post was read before the comment was posted. NOTE: There is nothing worse that a blog comment that says something like "Hey, great article. Check out my site (link)". Blogs I would like at least 25% of the blog comments to be on pages that do not have a 'no follow' tag. I will provide a link to a free toolbar that allows you to see the no follow tag at the click of a button. The list of blogs will be sent to you by Google Alerts. Chat Forums I would like you to post a minimum of eight (8) times in each of 12 chat forums for a total of 96 posts. I will provide the list of chat forums. NOTE: I do not want a link added to my site in any post until the fifth or sixth post. Your role is to post a thoughtful 40-50 word comment within an existing conversation in the chat forum. At the end of the project I would like you to provide me with the login information (username & password) for each of the forums. Summary In summary, you are bidding on a total of 100 blog comments (25 per week) and 96 chat forum posts (24 per week). I will provide a list of the chat forums. I will provide you with a list of suitable keywords for Google Alerts to provide you with a list of blogs. I would like you to quote a 'weekly price' for 25 blog comments and 24 chat forum posts over a period of 12 weeks. I look forward to seeing your bid
