Well, welcome to the forum and hope you contribute positively to the growth of this forum.  On your issue of no budget for marketing, in some ways,  there is no way you can set this up or run it with no budget atall. Even if you don't have much, few fee are still needed. But you can run bounty using the bountyhive services cause most bounty is being frowned at in this forum. You can pay the hunters after ICOs, if your project is genuine and outstanding, you will find bounty participants.
