I'm not an engineer outside of the occasional WP site, but that's enough. Cold email is my bag and I'm a good (and proficient) writer. In October I started cold emailing internet, marketing, and SW companies asking if they needed any help with their blogs. In the intervening months I've added 7 clients that pay, on average, $700/month for various help with content. MOst of it is blog posts but I also do press releases, eBooks, etc.
