Can you look at a recent Directory of the American Harp Society? One of the benefits of being a national member of AHS is contact information for harpists from 20 foreign areas, who joined us!! Under France I see six names; under Italy, also six. Privacy means I cannot pass these on, but a harp teacher might let you copy down the contact information of those professional harpists who live near St Remy or Agrigento. Internet information will show you which ones are located near where you travel, and which are too far away. None are located directly in those two spots. Another option: type in Danielle Perrett in your search engine. She is a renowned British harpist who has adjudicated harpists for certification in levels of harp proficiency, for many years, all over the world in many countries, including various places in France and Italy. She could perhaps know of harp rentals and teachers in your preferred areas. Good luck!
