Italia Startup Visa
One piece of advice from an Italian, who was born and grew up there: It's a suicide, absolutely do NOT do this.
We have the best weather, culture, food, wine, beaches, etc, you name it. But opening a business in that dysfunctional country? RUN and don't look back. 
Between fiscal pressure, crazy laws and compliances, the effective presumption of guilt, completely broken or unavailable infrastructure in the hand of monopolists, it's outright suicide. Companies will favor "friends" and deny you a chance even if you're competitive.
Oh and we haven't touched the criminal issues at all. I was lucky not have the pleasure of such acquaintances but don't worry, if you become large enough or successful enough, they will come to you.
