Embedded Mechatronic Design

I am in need of an experienced electrical engineer to assist with spec'ing an electrical system.

The system design.

-I am needing to control a Nema17 stepper motor and 300watt BLDC Motor.
-I already have the motors selected and the drivers for each motor.
-I am wanting to use an arduino microcontroller for the controls.
-I require the power supply to be as small as possible, but still being well within in a safe range of the power demand of the system. Refer to addition info regarding the sizing, or have a discussion with me on possibilities.

-Additional peripheral components: 3 x Push Button, 1 x power switch, 1 x small display screen. 2 x Limit switches.


What I need done.

I need a freelancer to design and spec the unspecified components around the ones that are already spec'd. You will need to spec the PSU, and design the PCB board for the micro controller and for the peripherals required.

I will buy all the componentry based on your specification and do the programming myself using arduinos firmware.
