Here is a link in Italian to an Italian Apostolic Ministry. Let me start getting some of these up and hopefully you can at least get some phone contact.
The UPC PAW and the biggest group The APostolic Assemblies all are listed with a few others in the last link I am sending
Not real sure about this though It is a oneness work

This is the site of the UPC of Italy. It is under construction but found this list of churches their locations and contact info
http://www.upci.it/DoveSiamo2.shtm#ROMA
The following is an article on Oneness Movement and the great thing about this link is it is actually a PORTAL to several Of the Leading Jesus Name Works in the nation of Italy. Play around with it, the works under the Apostolic Asemblies (The Hispanic Apostolic Organization) are the largest and fastest growing most established. Large assemblies especially in Sicily particularly the Palermo Work which also has a website in this portal.
Hope this helps.
