I admire your honesty and stick-to-it-iv-ness.  I don't know if Poser stuff 'sells' on its own merit, but as a businessman I can say with confidence that we'll buy anything that helps us sell product.  Have you considered generating work for your local business community?  If you come up with something interesting for 'XYZ Plumbing' they might be happy to pay you for your efforts...and, as W.C. Fields once said, "From the acorn grew the mighty oak."
