Those are wonderful covers, @CW Author!
I don't know if this is too private a question to ask, but I've always been curious. How successful has your self-publishing venture been thus far in terms of sales? What's Amazon like when it comes to exposure? Do you have to do all of the marketing yourself or is there some kind of recommendation algorithm you can try to game, like YouTube has?
Great question, Hank.
I can say that in my experience the toughest part is the 'start up costs' paying for a cover artist and an editor specifically. The sales process is mostly trying to make back the money you spent to release the book, which also is burdened by any money you spend on promotion (ads, etc).
I can say with my book I got very lucky on the editing side, and was able to save a ton of money and I was pretty good at shopping around for high-quality artwork that didn't break the bank, so to speak.
Without going into hard numbers I can say that I've made a couple hundred dollars profit after all my expenses over the span of about 7 months. So a great hobby to make some spending money but nothing in the way of 'making a living' at least not at my level. But then I'm fairly new at this and I'm still building my mailing list and doing promotion where I can.
I know some folks who write addjacent to my genre make up to 5k a month mainly just by being very consistent, writing to market and putting out a LOT of content consistently. People really like series in the E-book world.
