Ask HN: Startup Monetization Consulting

Just wanted to get people's opinions on an idea I have.

I seem to be very good at understanding a business and being able to figure out how it can make money. I'm not just talking about the traditional ways to make money online (advertising, subscriptions, referral or transactional revenue sharing). The first idea that comes to my mind is something that no one has ever mentioned to that company.

Can i turn this into a consulting business? If so, what is the best way to approach starting it?

Thanks in advance, Eric
