"The problem is probably that most good 3d modelers do not need your service."

How so? Don't 3D modelers need a platform to show their work just like graphic artists?

There is totally a place for this on the web, just because you use 3D models on the desktop doesn't mean they dont belong on the web in interactive form.

Have you ever been on a 3D modelling community site? There are amazing models, but you have to ask to download another artists work to really see it, and they likely wont give it to you. Imagine if all those artists (yes there are thousands of them) were given a platform to share their work in 3D??
