I don't know if there are any freebies out there. As for making them, that's a different area. Anyhoo... I just made one not too long ago, but my modelling skills are somewhat lacking.

All I did was take an abdomen and remove some polys to get the belt shape in Rhino. Save. For the gilt (metal), remove polys from your belt until you're satisfied. Save that too. I took both into Amapi and thickened them, just enough to give them depth. Save. Map as needed. Time: under half an hour.

You may need to subdivide your mesh(es) to get the best shape, especially for the gilt. I didn't bother making it posable or anything, though I probably should do so for wearing the title on the shoulder or holding above the head. And even then it would probably only require a a total of 3 to 5 groups to accomplish that. Again, that's a bit more on the modelling side.
