I have 300 members to help me, and I have resource to get do-follow comments blog. Do you think I can start this business? If I provide 1000 comments max and hit on the high pr blogs and so on. 100 comments - $25 500 comments - $120 1000 comments - $200 Do you think this will work?
I think there is already such service are operational there, but nothing wrong if you offer thoughtful comments, even there is chance to raise your price that you have planned for.
I would be interested also as long as the comments are worthwhile to the blogs you are commenting on, and you have the knowledge required to post comments that aren't going to be deleted.
