I was wondering if there were any regular columnists on this board.
Ages ago, but the model I used has changed.
In the early 1980's I wrote a regular column concerning small computers for business use, microcomputers at the time and mostly IBM, Tandy or Apple II systems. I had a list of about 500 local newspapers in the country and would routinely mail each column to about 150 of them. None of them had a local computer column and most had no dedicated business writer. I would send them the copy and get paid $5 if they ran it. Some ran one weekly, some monthly and so on. Brought in about $100 a week (after postage costs) and sometimes more, not bad for the time.
Today, you'd write a blog with that and try to monitize it with Amazon, Google AdSense and eBay affiliations. Probably for ten percent of the income. Pretty much the reason I no longer do this. Last column I wrote was for a state-wide business magazine and that ended in early 1990's when they got bought out and went a new direction. Paid $100 a month.
See what your local paper might be willing to accept, even for little or no pay. It'll get your feet wet. Or, start a blog. Same thing now days.
