Design a 3d graphic for my company brochure

I have a company where we produce our own Home automation system (intelligent lighting). For our brochure, I require a visual example of a typical room/living room which shows the wiring of our system. I have attached a picture which shows VERY BASICALLY what I am looking for. Please - understand - if I get something that looks like what I attached I won't want it. I can not design, and I can not draw. Your work must be many times better than this. You have a much higher chance of being accepted if you include a sample in your work, and explain what else you are going to do to make it better. You must read [[login to view URL]][1] to understand the system, basically. The idea is that all lighting is wired/attached to a box which sits hidden from sight flush with a wall. Then, all our switches can communicate with all the lights WIRELESSLY. You must demonstrate visually the fact that switches talk to the dimmer box using no wires at all. If you want me to add the wires that are required, I can do that. Also a simply Android powered smartphone should be in the picture, perhaps being held by a hand, which can also communicate with the lights in the room. Should you require any additional information, do not hesitate to contact me.
