How to get wheel designs to manufactures?

I am a freelance designer of automotive wheels. I have a couple of designs I would like to get manufactured. Does anyone know how to go about getting them manufactured. Any advice would be greatly appreciated.

will you can hook up with a oem or trading agent that will take your design and make it in asia. in one form or another. if you want just the rims dont like for 1 set you can check out tons of custom places in california or so cal that does it as well.

call each company up and ask for the product development manage and try to sell him your design

I greatly appreciate your reply and information.
