I have a tip from the trenches. Just about every site he looks on will have ads for writers. On one hand, freelance writing is a good way to make money and the jobs are generally great intros to working remote. Hell, freelance writing has been 'remote first' since before people even knew what remote was.
However, these same sites tend to attract bottom feeding pieces of shit who will offer insane rates like $0.05 per word for articles that require a fair amount of research. $50/1000 words isn't much and generally equates to significantly less than minimum wage.
Complicating matters, many pubs (including famous ones) are absolutely shitty clients. Net 30 is a pipe dream. Most of the time, you should be happy with most of net after eighteen emails to your editor. Those $0.05 per word sweat shops will generally want at least three treatments before picking one they like enough to do six rounds of edits on. And, about half the time, your article will never go anywhere and you just won't get paid.
