GEN VII: USUM: LF Ash Pikachu

[MatNX]

Hi there!
I'm working on a living Dex with all forms, and I've almost completed it! I'm only missing the following pokémon:
Ash Hat Pikachu Unova
Ash Hat Pikachu Kalos
Ash Hat Pikachu Alola
I'd want all of them to be legit, as in not hacked and not cloned.
As I've collected every other pokémon, I can offer all breedable pokémon there are, for you to complete your Dex. (This includes Phione) To clarify, this means all pokémon, not just the ones from Alola. As it is a special pokémon, I can also give you multiple pokémon for it.
If you have a Pikachu to spare and want some pokémon, please reply.

I know for one that the codes for these forms of Pikachu are expired and no longer obtainable, but there definitely could be some out there who have them, but the chances of trading them is low since the forms are not available anymore.

I know, but where else should I look/ask for them?
