Design security and surveillance camera systems for businesses - FREELANCERS WITH PHYSICAL SECURITY DESIGN EXPERIENCE ONLY

I am looking for someone who has physical security design experience. I have a business that needs surveillance cameras, access control, alarms and we need to provide them with a drawing for that. The freelancer would determine placement and application for the devices, draw them on a plan, and then I would have my installers install according to the design I would provide them with a floor plan that was done by the architect and then they would place icons where the devices should go This may seem like a simple task but actually the person needs to understand security design and how security devices interact with the uses for the space.
