Virtual tour hosting solution project

We are launching a new real estate website and need to have virtual tours at 360’ and floor plans available. Our agents will create the 360’ photos with their camera or Iphones and will upload them on our server with an admin interface. So this project is related to the development of the solution to upload and display the virtual tours (not creating them). I need a solution that enable to create a unique URL per property that I can integrate in our system so when I click on the 360 button it displays it as a pop up or in an Iframe, for example: [login to view URL] It is important to also note that we need to be able to map the photos on the floor plan as per the example. Here is another good example: [login to view URL] There are no restrictions on the technology, we will need a multiple user account admin interface which allows the agents to manage their own properties only. It is also important to be able to display the virtual tours and floorplan on mobile devices (Iphone, Android, Windows 8) Can you reply by giving me an idea of the time frame, budget & technology that will be used. Thanks in advance!
