Hexacopter (6) Drone Helicopter Robotics System Kit Design Hardware (and Software if possible.)

I currently need to have an octocopter or quadricopter designed from scratch. This is a very tough project because everything must be done from non-copyrighted material and must meet a set of criteria, specifications and standards. An example of what I need done is very much similar to 3DR ArduCopter Hexa-C and Parrot : AR Drone 2.0. I will also require parts lists and materials used. This isn't something I expect to be done immediately and will require perhaps concepts and design stages. My specialization is managing, so I'm unsure if a software engineer is required to work with. It would be great if someone could do both! My project needs to have the following features: USB port for data storage. HD Camera output. Speaker output. Screen output. LED output. Quiet running when in use. Large battery life. MUST have 3G connectivity to be controlled from either smartphones or a controller. Easy to use. Ultrasonic sensors. Replaceable parts. Please note my budget doesn't mean I can't stretch but usually I will pick the cheapest freelancer. Please contact me if there's anything I've missed out or if you have any other questions.
