Congrats and welcome! I have to say I have no idea where the area is that you're getting married, and I had to look up where it is. Having said that, I did look up vendor reviews on this site - you can do it as well - but found two that seem to have been recommended by other brides that were married in Italy. Keep in mind that firstly I have no idea if they are near where you're going to be, and also they could have changed since they were posted. I can't post links due to restrictions at work so you'll have to copy the links yourself:
www.imag1ne.com (yes that's a one I the website address) The fellow's name is Andy Turner, a Brit that relocated to Umbria. This is an old post so I don't know if it's still current or not.
There were a couple of brides that suggested taking a photographer with you. I don't know if that's an option for you.
Definitely use the search bar up top. If it's a question that has been asked on this site in the past, it will come up when you do a search.
Good luck and happy planning!
