Where would you get "something like insulin," in order to sell it at a reasonable price? What's reasonable?

I think that translates to about $38 for a 10ml vial.
As a drug company you would manufacture it. Charge less for it than what others are charging.
If the price of insulin is as outrageous as the article claims, that’d be easy to do.
If not, then it is priced correctly.
