I don’t want to dissuade you but be aware that many people in the small towns in Italy speak their local dialect, not Italian. The dialects can vary town to town, as do the accents. I could barely understand my cousins when we visited last year between them throwing in dialect words, even though they were making a conscious effort to speak Italian, and the speed in which they spoke. And I grew up hearing and speaking Italian my whole childhood.
I spent a year doing Duolingo as a refresher before we left and I was fine in hotels, restaurants and tourist destinations (and reading), but felt far from fluent when trying to have meaningful conversations.
I’d encourage being realistic about what you can learn in just a single year.
