I can take a crack at retopoing it for you. Strictly algorithm in either mudbox or Zbrush. I have retopoflow for Blender but thats very time consuming, its manual retopology. Very cool but still some work. I find it meditative though. I use it a bit for making clothes ( what little I've made) or fixing some of my basemeshes that I hoard. The results with algorithm retopology aren't "wow beautiful craftsmanship" but more like "hey it's the forms in less than a million polys at a button push and a few edgeflow guide strokes"
