Is there somewhere I can see a diverse range of plating options?
The Art of Plating is pretty good. They have a website, but I recommend their twitter feed.

Other than that, I would refer to plain google searches. Cookbooks are good inspiration. I think that amongst books, Essential Cuisine is supposed to be one of the better ones for plating (albeit I don't think you would go wrong with something like The Fat Duck Cookbook or Noma: Time and Place in Nordic Cuisine).
