If you like the idea of a licensed guide like me, along with the ones mentioned in Rick Steves’ book, consider contacting my good friends and colleagues (listed in no order of preference):
* Ilaria Ceccarelli at ilariacecc [at] gmail.com
* Sonia Tavoletta at soniatavoletta63 [at] gmail.com
* Alessandra Mazzoccoli at alemazzoccoli [at] gmail.com
* Wally Zanchetta at wallyzan [at] gmail.com
* Marta Marsili at martamarsili [at] hotmail.com
* Richard Bowen at rbowen [at] libero.it
They are all experienced, speak very good English, and I think highly of them.
