I'm not sure who can actually complete on those platforms and actually take pride in their work. I'm sure some people figure it out, but that's not me. I cant design and build you a scratch website for anywhere close $300 or whatever nutty price others can do. Also if you're American your competing with others in much cheaper cost of living areas its just not feasible for popular development work. I have to assume other people resell this work because it can be so absurdly cheap.
