The site is going to display different IT companies (not home for the elderly) - but the site for the elderly homes ([url removed, login to view]) looks just like the one i want!
Its build on a wordpress - which i also find easy to use and edit. I just was not able to find the used plugins - so they must have build it.
The geographic search should also be the same. But added a search for single words and "work functions" - in the different companies.
