3. Blogging in High-CPC Niches (Finance, Investing, Legal)

10. Short-Term Rental Host (Airbnb, Vrbo, Booking.com)

12. Remote Tech Support or Consulting

If you have IT, software, cybersecurity, or SaaS expertise, businesses will pay for hourly troubleshooting or ongoing contracts. Practical experience is valued as much as formal credentials—especially in finance, health, and legal tech sectors.
