What should be my mafia offer? Any growth hacker here

Hi IH's,

I am building an app similar to Meetup. But it will have all the features of meetup as well as eventbrite with affordable prices.

I am looking to put together an offer for my early adopters. Something like $99 for lifetime access to our platform to manage a community.

In order to do that, I am trying to figure out a mafia offer tag line.

For example if I was working on a job portal then I would write

"Get your dream job in 60 Days"

Any growth hacker here who could suggest me a mafia offer tag line?
