He has some very low res modles (eg Jane pictured above, or Lettermen), and would probably let you use them for free. The following is a quote from his site:

"If you are looking for a model and have failed to find one in Renderosity's marketplace or freestuff, or anywhere on the net, contact me for a price. Generally I charge nothing, or only a few pounds providing I can post it at a later date on this site."
