Aluminum blanks cut to size, where in the PNW?

[laminar-flow]

In an effort to reduce the time spent rough cutting sheet material and pipe / tube to size for machining, I would like to find a source to supply rough, ~ +.100" over, material closest to Seattle, OK, let's make that the west coast.

Parts are usually under 12" square and pipe / tube are usually under 6" diameter.

Quantities are from 5 to 200 pieces at a time.

Any recommendations?
