Introduce CiviCRM in Italy
I can only give my experience in Hungary.

When I started contributing to CiviCRM first I translated the strings in Transifex. I took me a half year to translate nearly all strings. 

Translation needed me firstly, beacuse we can use Civi UI translated. 
See the Italian pages:
https://www.transifex.com/civicrm/civicrm/language/it/

Later I translated some presentation and tried to spread words about CiviCRM on Hungarian forums, and sites where I can find interested guys. 

Visit the Get Involved page: https://civicrm.org/get-involved

The whole documentation translation big chunk of work.
