People are turning to audio and visuals when it comes to technical subjects. However, you should consider doing an ebook first and turning it into an audiobook through a resource like Audible's ACX platform. You can hire a producer either through a royalty share program, so you don't have to shell out upfront cash, or you can do a pay-per-hour hire as well.
I support bootlegging – I don’t see it as being immoral or unethical in any way. I used to bootleg quite a bit in my youth, and I still do on occasion today (although not yet today in particular, I more meant “in the present”). If you want to hustle for your money, do what you must, baby. Download some software, music, movies, or other assorted digital goodness here and start slangin. It’s not an easy life, but sometimes you gotta do what you gotta do.
Your Brand Persona and Target Audience. When you eventually start creating content, you have to know who you’re talking to and tailor your brand voice to appeal to them uniquely. If you aren’t targeting the right audience (those people who will lean in to hear what you’re saying), you won’t find success. And, if you can’t find a way to stand out, you’ll blend into the hordes of other brands competing for attention in your industry.
