Android Unity 3d Augmented Reality Application Building and Menu

As you may have seen i have another posting for same app this one is for multiple buildings. I need an android build of of an augmented reality application. I have listed some sample scripts down below but you are more than welcome to write your own. . User needs to point camera on smartphone to look at a building and replace with a 3d building model i have already designed. I need this done for 5 buildings joined by a main menu with each building name to choose from. Also is picture of 2 of the building below needs to work with, keep in mind I have the 3d models made for each in max and fbx format . This is please only for unity professionals. Need also a basic small menu for navigation. I need to see proof of experience before we begin any talks. Thank You for Your Time
