You could try the following in Italy. I can't say whether they will export or not. A lot of nursery owners speak of Italian couriers not being insured once the plants leave Italy and so they are unwilling to transport the plants.
I got the information below from the list of vendors at the local flower shows
http://www.floracult.com/home.aspx and
http://www.laconservadellaneve.it/home.htm. For anybody in Rome in spring, Floracult already has information about its show in April this year. Not so "La Conserva della Neve" but check for updated information every so often.
I can't say which of the following will be able to speak to you in Spanish or English. Give them a try anyway
