I immediately understood why you are asking me about the exhibition.
It was not difficult to do)
There it is easiest to find partners, but this is not the only way out. If your project has prospects - you will find investors without participation in exhibitions.
But at public events and exhibitions make it much easier and faster.
I think that it's best to do a large-scale advertising project on the Bitcointalk forum. It is here that the necessary audience is present.
Advertising on the forum has long been underway. Developers have previously launched a bounty campaign.
Of course we will attend public events. It is good to talk with people and on such events it chance to find a good team member or adviser.
I've written a few tips for you. Take me to your team. I would gladly work for the benefit of the project. 
I can sing beautifully and play the guitar. Take me to the project team)
Seriously, what kind of specialists do you need?
I can be wrong, but first of all, programmers and experts in advertising and marketing are needed.
