Isn't this a little bit early to find and start a bounty/signature campaign?
Most ICO lasted around 3 months, this is usually when bounty/signature participants received their tokens.
Anyway, I'd recommend Lauda or Yahoo for running Signature Campaign.
I'm not sure whether Lauda still want to manage a campaign, but Yahoo are always open and both of them are highly professional

P.S. there are many mistakes and errors on your website, might want to fix that first.
