I think you are a little bit outdated about the rates, because it is so low for this forum.
The best campaign managers, like aTriz or Yahoo ar asking for more than 0.15 btc a week (aproximately $ 650 a week) newbie managers are going to ask for at least $200 - $300 a week, it is not easy to be a manager, you have to take control of all the users on the forum.
And 85$ for the signature codes ? it takes a lot of time to design them, you will have some newbies in here posting their concepts, but real codes are not going to cost you less than 0.04 bitcoins (aprox $150)
So your budget will define your project.
And i forgot to say, that you are only paying 30% of the rates in bitcoin, and 70% in your tokens, this makes this a weird project.
That's right
