I meant that if you were willing to count a few days a month as "not really working", then you can trivially bill $2k quickly. Otherwise, niche software is an option.

I think the parent meant you could make that much money as a consultant in a couple of days, not create a niche software product with recurring revenue.

To be fair, I didn't clarify a timeline. I'm just curious what HNers think would be the fastest option. Fastest could mean 2 years.
