Client, Adding textures to room 1 in Unity

As the models my other group member has created had textures that couldn't be used in Unity as they used mental ray in 3DS max i'm not going to texture the models to suit our theme of a futuristic supermarket featuring new technologies. something else I need to do is fill the scene with floating fruit, a dog wash and other props. I have also added the Morrison's logo above the Tele porter, this is the logo they provided in the project pack which the brief came in.

below are some screenshots of my process and also what I've done so far..
