Your looking at a very large order. I wouldn't use this forum for an order of this size. You can, but an order of this size will get you front row at any company. And I mean a top company.
You need to research through trade magazines at your local library for this topic.
Call the company DIRECTLY. DO not use a middle man on this if you can help it.
Are you sure you want this volume? or is it a misprint. Your looking at about 150 to 250,000$
