Forum and Blog relevant comments research and writing

Hi, This project is to build links and drive visitors to a website. There are two parts to the monthly project: 1. Research and find related blogs and forum posts (I'll supply the topics to look for, and provide guidance on the sort of sites) 2. Write and post on the blogs and forums and include links back to (our site) The comments have to be written in perfect English, be several sentences in length, be relevant and contextual (I'll help give you guidance on the sort of thing we're looking for) and that provide real value to the sites they are posted on. In some cases you may write posts that don't include links but that build your credibility on that forum or blog. I am only looking for comments on and links from established, respected, quality sites - so no spammy posts on spammy sites. I am looking for quality, not quantity, so 10 good links in a month is the target. If your work is good then there will be more Please include details of prior work like this including writing examples Thanks
