Assembly code for XC888 microcontroller -- 3

I am looking for a skilled developer who can write assembly code for the XC888 microcontroller. The code should control a specific hardware component, namely a motor. I do not have a specific motor control method in mind, but I would like the code to be able to respond to 12 push buttons and 2 potentiometers. The ideal candidate should have experience in writing assembly code for microcontrollers and be familiar with motor control methods such as PWM, H-Bridge, and stepper motor control.
