He is local to you, and is the largest Rays Wheels retailer in Norcal, maybe all of california judging from the pallets of te37's he gets on a weekly basis.
This dude stocks a ton of stuff and can get you anything from Rays/SSR/Works/other brands
I am fairly certain, for example, that Rays Gram Lights variants come in 18s and close to those sizes
Example of Gram Lights 57DR:

Comes in 18x9.5 +22 and 18x10.5 +12, basically right what you wanted
