Perhaps a real world example of who has done this and has actually MADE money???
I am not at liberty to disclose who those companies are, however. Some, I've signed NDAs with, and others I haven't asked them if I could disclose that they used subcontractors.
Worth adding that I was the first to be surprised that they managed it. I don't believe in outsourcing your core business processes. However, whether or not I believe it, they did it.
I'm not actually advocating this as a standard model, btw. I think if you're not technical, you should start a business that doesn't require lots of technical knowledge. There are plenty of those opportunities out there.
Groupon is an example of a huge technology business that didn't require all that much technical skill to get off the ground.
