Hi all - can anyone tell me where I can

Not sure about a brochure but,there's plenty of good books out there.

can you be more specific on what you are looking for exactly? 

Try a travel agency

If youre in London you can try the Italian tourist office near picadilly - or a branch of Thomas Cook .... 

Further to modicasa's answer, your best bet would be the nearest ENIT {Italian Tourism Office) and they have branches in many cities and countries around the world. Here is the link http://www.enit.it/en/

Rome cabs.com. Is similar to a limousine service, they will pick you up and drive you into Rome for a fixed rate. If your flight is late they wait for you no extra charge. They also will provide guided tours in and around Rome. Cost for taxi to rome $50
