I would suggest that you find a low cost microcontroller that's capable of running your PID loop. It shouldn't take much. You can probably use one of these with no trouble. They even come in SOIC which is much easier to solder than QFP. If you write the software for the PID microcontroller so that its inputs are "step" and "direction," you can use an existing controller and firmware with no modifications, except slotting in your driver and motor instead of a stepper driver.
