Offhand, I can remember three talented 3D artists, but I know there were more.

Mark Millmore has posted Dendera, and other stunning 3D renderings (with tutorials) at Mark Millmore's Ancient Egypt.

Djeser Hatshepsut is another fine 3D artist. I am not sure where her site is located, but you might want to leave her a message.

Finally, Bryce Yupanqui knows his salt. Back at AS, he ran The Serapeum. It was chock full of beautiful 3D graphics.

You can also find some up to date info on the latest software and some nice tutorials at Grafix Illusions.

Hope that helps. Best of luck with your latest project.
