Do you have your own coin to promote or are you going to offer yourselves to be a bounty manager, if it's the latter forget it, build your reputation here first and try to rank up I know you want to be a manager not because of the challenge because you want to make money right away.
It's not easy to be a manager unless you know the in and out of Bitcointalk, I may be too harsh but you have to see the reality here.
