Need Help Regarding One-Off Custom Designed Challenge Coin.

I wanted to buy a custom designed challenge coin, I reached out to a bunch of websites/companies and most of them only sell custom coins if you are willing to buy them at a bulk (at least 50 coins).

I understand why that's the case as designing and making a die just for a one-off piece is not really viable; however, are there any companies that are willing to produce custom-made one-off challenge coins? Most companies that do sell one-off challenge coins only use laser engravings, I don't really want that.

Thanks in advance,
