I called a place near me and asked how much it would be for a custom spur gear about 2 inches in diameter cut out of 3/16 steel plate. They said for 4 of them is would be $40-$50 apiece and would take a day.

Now, I didn't ask if they need a file to import but I assume they do. Now my problem is getting a proper drawing. Can MasterCam or Autocad do gear drawings good enough to cut from?

EDIT: One thought that crossed my mind about meshing the 32P with the Module .7 is that a 54 tooth 32P gear is about .200 larger in pitch diameter than a 54 tooth Module .7 gear. Gearing depends on the difference in diameter between the two "wheels" However, these "wheels" have teeth. The number of teeth is directly proportional to diameter of the "wheel." So in a situation meshing gears of different pitches, what makes the ratio, teeth or diameter or a bit of both? Doing this seems like one of those things that isn't supposed to work but it does.
