Side Project Idea

I want to take a raspberry pi and control two cim motors with it. Problem is I have no clue where to begin looking for a motor shield for two motors and their controllers. Would this even be possible? Also would I need a dedicated PD board for this? I would like to keep cost components and size way down. Thanks if anyone is knowledgeable about any of this!
