Hey! I will be excited if there is such a local fair around, but I doubt so. Nonetheless,
Verify is a promising ICO that provides escrow service since trust, reputation is in dire needs these days as the e-commerce services shoots up (companies doing businesses online). It is not in Europe, however, but I recommend you to take a look at the thread
Verify, and their
whitepaper.
Hope your fair success, and to see it in the near future! As for marketing, I believe this forum is a good medium to reach interested investors, so you can give it a go here too.
