Buongiorno a tutti, I need help in

Buongiorno a tutti, I need help in gaining Italian citizenship/residency. I am an Italian-American and have never been to Italy but will be taking my first trip there in 2020. I am more than certain I want dual citizenship and to buy a home in Umbria one day. What are the steps I need to take and what will the estimate cost be? Grazie to anyone who can help.
