There are very few reasons to outsource the security risks associated with storing and managing your encryption keys. Cryptographers are as good at implementing protocols as interior designers are at laying brick. The post-Snowden IT security job market has been vacuumed by armies of corporate and government recruiters. There are still plenty of people who are unable or unwilling to pass security clearances or pee in the cup. You can also pick up whole teams by looking outside the crypto space. Airgapping cold wallets without proper access and emergency procedures is useless.
