All freelancers should learn how to quickly assemble a simple SaaS (e.g. Bootstrap + Flask + Stripe) and then quickly implement a version of whatever they were doing in their paid projects (making sure it's legal ofc) and expose it as an SaaS using their SaaS template. They can even form a separate Delaware LLC for each of them, once the SaaS is built they can just try to sell it; lots of money there as well as not many people can build a company from the scratch.
