Source For Corian (or similar)

Greetings, I am trying to find a source for 0.25" thick Corian (or other brand ‘Solid Surface’ material) in sizes larger than what Inventables can provide. My current project requires 10" x 16", but not sure if it will be all white, or with some colored specks…

Any help on finding a place that sells custom cut or remnants is greatly appreciated.

Used to be a chap selling things he cut out of corian at the College of The Desert Market near Palm Springs, he told me that he got offcuts from kitchen counter installers.
Not sure if you have any in your neck o’ the woods.
