you might consider keeping your FT job, and as a side-hustle, subcontracting those "thousands of contract work offers" with third-world professionals acting as an agency.

Aka the easiest way to ruin your brand and deliver shit work. If the clients wanted work done by "third-world professionals" they would hire them directly; the reason they're contacting you instead is because you have some credentials, references, etc that the third-world guys don't have; now do you wanna bet all of that on unvetted third-world freelancers?
