We want a provider to build a website similar to vacation holiday websites. There will be two types of users - "Home Owners" and "Visitors/Travelers". Home owners will list and maintain their own property with calendar and Travelers will view and inquire about properties. Superadmin will be able to override/assist both types of users. The superadmin needs an admin control panel where he will be able to create different categories of holiday listings with different questions and slightly different display for users depending on the type of listing. Ideally site is done in drupal but if you know of different technologies, please state so.
