One last thought: if you do want to lift your revenue to the great heights of £200+ per year, a popular business model these days seems to be to serialise the work, give away a free instalment every month or so, and invite people to sponsor you. I know you hate the tech side of it, but if you can find someone to whom the phrase "Wordpress blog linked to Patreon" is meaningful...

And thanks for teaching me a new word! (Actually I suspect rather an old word.)
