Assuming you can create the poses, and if not it's way too soon to be thinking of selling, just create a new category in your Pose library (at the bottom, or is it top, of the pop-up list of existing folders in Poser 4) and then with your figure selected hit the plus sign at the bottom of the library bar to save a pose to the library. Gather a set of poses and you have a product, remembering: if you need to move the figure as a unit, for interaction with another figure say, turn off IK and move the Hip - changes to the Body aren't saved. use P3DO to make PNGs from your RSRs if you are using Poser 4, or RSRs from your PNGs if you are using Pro Pack or Poser 5. make sure the pose names reflect the figure used, and ideally the nature of the pose: 001.pz2, 002.pz2 etc. is unhelpful.
