Who do you contact for permission to sell reproduced NHL logos to sports bars etc. these are unique designs?

We own our own home based business doing metal designs and made some hockey logos for fun, now everyone wants them. Hot item. The only thing is we can't sell them as they are a trademark. I've searched everywhere I could possibly think of to get permission, sign a contract.whatever but I come up empty handed. Would of liked to have had this for christmas, but if it helps for our marketing strategies for next year, that would be great. Anyone with suggestions???
