Oh, that's too bad! I remember a project I had and it took a zillion calls before I found the material in California, NOT where it was expected. But I got all sorts of "amusing" answers to whether people on this coast (I'm in Maryland) had it, that the project wasn't possible here (that's allegedly why they didn't have the material) and your minimum order of 500 pounds (when I finally bought 2 pounds :-) was the answer somewhere else.

I hope once you get all the materials and get them ground to the right specs and line up the furnace, etc. things go a bit faster for you!
