Different 3D Models incl. interior

Hi, I’m looking for different 3D Models which will be used within an app. The models should be available as a .fbx file. Below you will find the specific 3D models I need. In addition I need these models with the appropriate interior. The interior for the different floors can be the same / copied for all floors. For every model I need 4 different colors (blue, pink, green, orange) for the exterior and interior which need to be included in the specific building in a proper way. Some models I will provide and need therefore only the interior or provide models with interior and therefore only need the different colors (will mention it in the appropriate model description below). It would be great if you can give me an estimation of the full price and the time you will need. Would be also perfect if you can send me some screenshots of your available models (if possible). Thank you in advance.
