There are many places that do it, but quite a number of issues as well.

Yer talking about $300-$700 for a 6-8 inch tall figure. Ive seen priced up to $1500 for a 12" figure. The processes have improved so the quality of the produced items is pretty good now, depending on the method of reproduction, and the material they use.

Everything has to be closed geometry on the object done.. in other words things like transmapped hair won't work. Thge term they use is "watertight".

Since most clothing is single sided polygons, that also means you can't have clothing reproduced. Some props will work, others will not.

Also, by your content useage agreements, you cannot redistribute meshes at all. So no commercial items can be given to any rapid prototyper. No Daz, no poser base figures, ect.

Way too many people take way too many things way too seriously.
