Not sure what you are looking for but number of years ago I took thrift store barbies, and coated them in a couple of layers of snog rag paper mache. Glued their hair into an "interesting" dos and when all dry we stuck their feet into a disposable cup of plaster. When it was all dry cut the cup off and spray painted one in gold, one in silver and one in bronze. I suppose you can got the extra mile and find some cheap doll clothes and give them the zombie treatment.
Another thought is to hit up the thrift stores and look for someone's castaway trophy, tweak it some... maybe "cut off" the bowling ball so it looks like a lurching zombie or leave the bat in hand and dangle a tiny head from it so it appears someone whacking off a zombie head. Maybe you'll get lucky and find a runners trophy. Change out the little name plate and a new trophy is born.
