Need more Yukari

Ok. To put it simply, I have a sort of..... thing, for Yukari. (Yukari Yakumo, Touhou) Anyway, I am on a quest to obtain every Yukari doujin in existence. Or at least as many as possible. Would anybody be able to help me with this? I know this might sound crazy to some, but for me, this is like, a sacred pilgrimage. Complete with spiritual enlightenment at the end!

Yukarin + touhou + google should be the best solution.

character:"yukari yakumo" and limiting search to doujins brings up some 500+ results on ehentai. Start with that.
