Replying to where can i get boxes and rails made?

I'm in the process of putting together a terrain park for my local mountain (Blue Knob, PA)and was wondering if any of you guys know where we could get some nice rails and boxes. Everything we have now is homemade. We were looking at Straightline Rails in VT (www.straightlinerails.com) and their stuff seems decent, but they never answer their phone or reply to my emails so I'm not sure if they're still a company or what. But if would be great if you could enlighten me to some fabrication places with decent prices, where your mountain got its rails, etc.
