Rk3399 Computer on Board schematics and PCB using Altium

Need an Engineer to design the circuit schematic and PCB layout for a Rockchip RK3399 SoC.
This board will use a Android OS. All components used (wifi/bt /ethernet controller...) must have working linux drivers.

Board will need to have:
RK3399 SoC
4GB RAM - LPDDR4
SD Card
Ethernet Port - 100M or 1G, depending on component cost.
WiFi + Bluetooth - WiFi @ 2.4GHz and Bluetooth at rev 4.0
2 x USB 3.0 - for peripherals
2 x USB 2.0 - for peripherals
18 GPIO buttons
LCD connector. Best if RGB24, if can’t be used then MIPI DSI
HDMI Port
2 USB Type C Port – For power and data
eMMC – 128GB
NGFF M.2 SSD connector
4 ADC channels. 6 bit low resolution is OK. It's for joystick components.
As many available GPIO as possible.

Please keep PCB layers to a minimum as to keep cost down.
Engineer will choose the components and provide a BOM.
Engineer has to provide impedance control guidelines.
Engineer has to debug the board and make sure it works correctly and is responsible to correct any hardware mistakes or issues.

Design must be done using : Altium Designer Software

Preferably someone who has already done RK3399 layout.
