There is nothing special in starting, just hire someone to design and code signatures for each level rank you choose and that's all. But everything don't ends with it, main idea is how succesful it will be. For this you need optimal number of users and also good posters. For example you have something to promote, spammers can't help you in this situation, why? Because if post isn't interesting and no one will read it, no one will read signature also. But you need users, for example one mostly posts in economy, one in bitcoin discussion, one in gambling, one in all thread generally and etc, you have to determine what kind of posters you need to promote product better or just hire good manager which will do all that jobs well.
Yes it depends on the Campaign Manager you have appointed. Avirunes is the best campain manager i have seen him running many campaigns perfectly.
