I was thinking exactly the same model! Paint it in ogre skin colours and noone will know it was really an orc

Reaper makes cast metal minis. Bones is a line of minis that were re-cast in PVC plastic. It's VERY detailed, but it's a bit bendy. That makes them a lot lighter, and safer for children too, and easily moddable. They're not weak (slap), but firm, you can just bend them with your fingers, but they snap back in position easily.
And they don't require primer, you can paint base colours straight on them. People have tested them, paint holds very well if the first base layer is NOT thinned with water. Once that layer is on, you can paint how you like. Finish them with spray matte varnish (anti-shine from army painted for example) and the paint will not easily chip off, even when bending very roughly!
