Write 150 min PR1 creative and unique blog comments

I am looking for someone to write creative comments on blogs and post a link to a ecommerce site. The purpose is to refer sales from the comment, and not SEO-related. Please remember that the main purpose here is to write a comment that will GENERATE SALES! This is key. Rules: - the page you comment on has to be relevant to the industry of the ecommerce site you will promote, so a person reading the article on the page you comment on will at least be interested in buying the products on the ecommerce site. I will provide details about the industry in the comment area. - each comment should add some value to the discussion, while subtlety stating that you personally have used a service that solves the same problem described in the article; this should be done naturally and should not look contrived; I will also provide some examples of such comments - each comment must be unique, at least 4-5 phrases long - no generic/stupid comments please - the page must be at least PR2 or can be any PR if it is on a established site/blog (established site = min PR5 home page, min 5 years old) - the page must not already include a link the ecommerce site - should include just one link near the end of the comment; nofollow/dofollow both allowed; link can be raw URL - you will use a different name each time - you will use different "personas" when commenting (e.g. a young guy would say something like "Yo man this hasn`t worked for me but check this out...", old guy would say "I found this very hard to use as it is not...."); personas should vary by age, gender and nationality; this should obviously be reflected in the name. - need to have very good English skills; you can write in "bad" English only if you`re doing a foreign persona Please place your bid for 150 such comments. Also, please mention if you have done similar work and provide some samples. Once again, this is NOT a SEO-comment-spamming gig. These comments should refer sales !!!
