Corporate Buildings

[Bob120]

Well this may be hard, or not because I don't know how to make models and animate them is and I am being a bit vague, but I would rather like to have some corporate dark greyish buildings/building with no windows a main door and small spotlights on the roof about 4 in a line, that if possible could move from side to side slowly. And another building/buildings that is similar but has a turret on the top- which could be a upgrade animation or something, well that's it and I hope you can try and help.
Thanks anyway for even reading this.
