I2C motor controller board recommendation for pan/tilt camera?

I need to make a small robust pan/tilt camera that is controlled via I2C.
I plan to use two very small DC gearmotors to drive it, one in pan and the
other in tilt. The camera will be one of those small lightweight metal boxed
board cameras, you know, about 1" x 1" with a changable board lens.

Since the power requirements are very small, can anybody suggest a source of
a very small I2C dual motor controller board (or two small single motor
controller boards)? thanks for any help at all.
