Startup Idea : A medical services comparison site in Luxembourg

Luxembourg's medical system is based entirely on private doctors and medical service providers, but it's a minefield - each offers services in different languages (to differing levels of fluency...!), and they vary widely in customer service and quality of medical care. The problem is, there's nowhere patients can share their experiences with others and find recommendations. Everything is done by word of mouth, which isn't helpful to new arrivals to the country.
