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.
One of the most underrated freelancing sites ever. The site started as a place where you could get paid to do short tasks for just five bucks. Over the years, it has slowly morphed into one of the biggest gig/freelancing sites where you can now charge any amount to do all kinds of stuff for other peoples. Anything from serious stuff like copywriting, translation, voice over social media management to silly stuff like prank calls and everything in between.
Starting a podcast, like making a YouTube channel or blog, comes down to telling interesting stories and building an engaged audience. I’m probably sounding like a broken record by now, but you need a niche that you’re interested in and there’s already a demand for.

So, I started reading and learning about affiliate marketing and blogging. I combined the two and after a 14-15 months of really hard work (sitting in front of computer for 14-6 hours a day and putting things I had learned, into action (building a blog, writing articles, promoting the site, etc), I started making enough money that I started believing in myself and the idea that I too could make a full time income online. From then on, I just kept on going and the income grew and grew. Now, I still work 8-10 a day on my online business, and sometimes even more. You have to constantly work and maintain it. Most people think because its online, its easy. That’s where they get it wrong.
One of the cool things about Google AdSense is that it's so easy to get set up. If you have a blog or website, you can sign up for a free Google AdSense Account. From there, Google will give you a unique code that you will paste onto your website. Google takes it from there, tracking your page views, traffic, and earnings on your behalf. There is no upkeep or maintenance to get this thing going, which makes it a no-brainer if you have a website already.
