You could create a lead gen business utilising some of @Andy Black techniques
Interresting idea! Tough it would not work for me:
1) I am not a sell person, I am more a technical guy. So the lead generation thing is clearly not in my deck of cards.
2) I could of course become a professional drone pilot and sell my footages / services. But it will fail the CENTS commandments, especially Time, as I cannot scale. Basically it would be a job.
3) My failure teaches me to not burn my passions.
