I'm not aware of any Dutch miniatures for this period, but his uniform is similar to French hussars of the same era, albeit with a shako which is a bit higher than the kept which they wore on campaign and perhaps a bit lower than their own shako. It's more like that worn by the Chasseurs d'Afrique, but their unform doesn't have the frogging.
Neither has the plume of course.
I think your best bet would be French hussars from the Franco Prussian War range by the Perry's. Perhaps building up the Kepi a little with some miliput and adding a plume.
