it's unlikely you'll be able to produce a real hardware PWm using hardware PWM module (HPWM), you'll need to use a software PWM, easy to build with Timer Interrupts.

One way to go is to use the following

Not with a PIC16 or PIC18 you won't. What is needed is a PIC with a 16-bit period register. With any of the 24-bit core devices, you can get below 10Hz easily with 16-bit resolution on the duty cycle.

I KNOW.. it's just not PBP related ;)
