I don't have a specific recommendation , but one thing to consider when choosing your model is not necessarily going for a high polygon count, as most renderers provide you with a "smooth polygons" or "subdivison" option when rendering, so the polygons are only smoothed when you render, leaving you with a lighter model to work with in the mean time. A well designed lower polygon model (which subdivides nicely) can be better than a super high resolution model. Just something to consider when making your decision.
