Santorini Renal is a new dialysis center in Santorini, Greece. With this new unit, people with renal problems will be able to have their vacations in Santorini which was impossible until now.
header with the logo and picture from santorini (in a way that the health unit doesn't lose its seriousness).
Also on the header or wherever you see fits, put flags for greek and english.
horizontal menu under the header with buttons: Home, Services/Treatments, About Us, About Santorini, Contact Us
Content in three columns (left with modules such as latest news, articles etc.), middle column with main content, right column with a banner of a featured news item like "We're open", "Contact Us for more info" or whatever you think of to fill that column.
The above is a possible layout I have though of, you may come up with something better.
Generally, I like clean layouts and in this particular case, we need something to imply that people can trust us and also that this unit is in Santorini (one of the most famous tourist destinations in Greece and the World).
Feel free to ask questions, I'll be close to the contest and provide feedback.
