Just contacted a campaign manager.
But for my understanding... it is necessary to have a campaign manager which cost around 0.05B a week???
Thats more than $1000 a month which is insane and we could use this money to invest in ad campaigns on social media and Google Adwords.
You can start signature campaign by yourself, if you will pay in BTC then people will definately join your signature campaign. Also sent PM
Edit: you have only iOS app?
