I'm a freelancer and cloud computing consultant, I charge $200/hr. At this point I want to diversify my income, have some semi-passive income or more scalable incomes maybe. For the last 5 years I've tried to launch a few startups, I have no problems with persistency, but it seems I suck at finding PMF.What else can I try? Something based on my expertise. I thought about:- Courses about cloud computing. The target audience is small, yet the topic is lucrative, so, I guess I can price it significantly above average. Also, I have ~$10k worth of audio/video equipment. I have no audience on social networks, but I have a lot of cash to experiment with ads.- Youtube (cloud computing). The target audience seem to be way too small to payoff the efforts.- Podcasts. Freelance, maybe high-profit freelance specifically. Podcasting still looks like wild west, even though i'm listening to podcasts for 7 years. Not sure what is ROI here.- Marketplace software? I heard about people making slack/telegram/discord bots, something else? No idea what is ROI.Any better ideas?
