CCTV Installation

I have a site I want to fix up a couple of cameras on a factory complex, (fictitious of course). Drawings would be supplied on request. I would need approximately 18 cameras on site (indoor, outdoor, PTZ). I want someone that can help me identify where to place the cameras and choose the best cameras for the application. Lens calculation would come in handy here. The report should include drawings, design analysis, lens/design calculations and should explicitly state the methods from hanging up the camera brackets, running the coaxial cables, fixing up the DVR right down to connecting it to the monitor. Safety consideration/procedures should be included.
