I have two notes:
- One person can't run successful project, you may hire some marketers and developers to work with you, this point depends on your budget as well.
- You should create a good bounty system, the bounty hunters will help you to advertise your project, but you should do some steps in order to avoid spammers.
Bounties are good, but this forum has way too many under-qualified scammers and those that boost themselves up and produce no results.
