You might want to check out other 3d apps, as the tools work differently which each app. ZBrush might suit you better since you work with clay.
Instead of a 3d scanner, you could also go the cheaper but more work route with something like
http://www.photomodeler.com/ or Realviz Image modeler
http://www.realviz.com. You can create your models in clay, photograph them at different angles and suck them into either app and layout those polys.
You might also want to check around your area for studios or graphics bureaus as some do provide 3d scanning services.
