Circuit & JBL Diagram & Schematics for a miniaturized PCB Design

Hello. We are working to create a wearable glass design and we need a Circuit Diagram along with JBL Schematics. The PCB Fabrication will be done by our end and is not part of this project. The circuit is not to be designed on a development board and it should be a complete circuit that can be implemented directly. The circuit must have: ~ MCU/MPU ~ Two Buttons (First for Power on/off and Second for Time-Delayed Action) ~ 2 Cameras working simultaneously ~ Mic & Speaker (Bone Conduction) x 2 ~ GPS & GSM Module - 4g VOLTE/LTE compatible ~ Power Management IC for distributing power to MCU/MPC and peripherals ~ Capacitive Touch Interface (Minor Size) - Not a screen ~ We need two variations i.e. two circuit designs: ~~ (a) 2 OLED Screens of 2.5 inches or 1 OLED Screen of 5 inch ~~ (b) Pico Projector without LED Screens ~ Battery (500 -1000 mAH) ~ Bluetooth 4.0 ~ Wireless Charging capability(Inductive Charging) ~ Storage (4 to 16 GB) via eMMC Module ~ JTag & other interfaces for directly connecting the circuit to a computer for debugging. The circuit/PCB will have functionalities including ~ Graphical Processing (OpenCV) ~ Voice Processing (Using Audio Codecs) ~ Taking image and storing them ~ Streaming Video ~ Internet connectivity for cloud application connections We need a complete circuit with documentation mentioning all the components as well as justifications for using them. You can use Proteus, KiCad or any other tool but do let us know about it in advance. If you have any query, feel free to get in touch with me.
