These are all one-of-a-kind and I still have them (and several other Pokeponys) on my etsy.
Sale permission grandfathered here.
If you'd like a commission for one of these (or a pony of something else) feel free inquire. Unless you're after something INSANELY complex (like Reshiram or something) 40 is my price before shipping. My turn around time is about 2 weeks, max 3.
