The Business: Make This Happen Before Someone Else Does

This needs to be made.

Call it "Hero Delivery Service" (because global trade reasons), and write the story of the guys who drive the trucks that send isekai protagonists to their destinations. Write it as a dark comedy, and have the truck drivers be thinly-veiled former antagonists who are serving cosmic sentances doing this as a form of Purgatory, knowing that they are contributing to the final defeat of all evil everywhere by their actions, and thus the futility of doing evil.

Good comedy is hard to do, but evergreen when it is done.
