Hello, I can provide comments that are relevant to the subject and also engage the other readers of the blog. In other words, comments that will be approved by moderators. I do this kind of work for other clients. I know what nofollow and dofollow is all about, and understand your needs. My price is $2.00 per comment (usually of 100-150 words.) 50 a day is no problem at all. If you would like to see some samples of this kind of work, let me know! Many thanks, Ryan Peter.
