Download Blender 2.71, it is free, and search youtube (or other channels) on sculpting tutorials in Blender.

In all, it took most of us 1 to 2 months to master the "basics" of Blender to make morphs and sculpts  for Poser/DAZ figures.

I came from Hexagon (another 3D modeler app) , and could do the above in a few "study" days.

Good luck, some patiance, and you will be rewarded.
Best regards, Tony
PS : there are some good Blender forums to get you going too.
