[ContractAuction]

www.contractauction.com is a free website to connect manufacturers and purchasers. We also now have a Non-Disclosure Agreement that can be used when posting work that ensures anyone viewing your listing has agreed to the terms.

From the site:

One goal of Contract Auction is to increase production in the US and Canada, be aware when you are bidding that you will not be bidding against foreign countries. While we realize there are some who prefer to outsource to foriegn countries there are still thousands of manufacturers in the United States and Canada who are capable of providing the highest quality parts at a competitive price.

Are you going to be actively enforcing this policy? How?

[ContractAuction]

Great question! We monitor the website constantly to ensure that only US and Canadian users are posting or bidding.
