As I mentioned in my first post, I have a complete Arctodus model, except without animations. I also have a Dilophosaurus model, and an Eolambia model, and I'm working on a Uintatherium. Do you have any advice on how I can market my models?

You'll probably find a larger market for your models over on the user forums at blenderartists.org , than here on the developer forums.

You might be interested in joining the Blender Network for professional services. Also, there are a number of sites that offer or sell 3d models. Google is your friend here.

stiv, I followed your advice and looked at some websites with that purpose in mind, and was able to find some sites that looked promising. Thanks.
