Generally speaking, most CEOs will respond positively to an offer that they put $1 in and get ~$3 out (with a range of possible outcomes around that ~$3). In fact, most smart ones will ask how many $1 bills they can throw at you before this proposition becomes untrue.
People who have the kind of combined skill set that 'patio11 has are relatively rare, but they need not be as rare as they are. For many people, all it takes is adopting an appropriate mindset for their work.
Location simply doesn't matter unless you are in a place where CEOs don't like money.
Edit: actually, first thing you need to do is stop charging by the hour, and charge by the day, or better, by the week.
Based on my past experiences, I'm not sure making lots of money is my goal, but I have the nagging feeling that it should be possible, just because it was no secret that people will pay that.
When I read the blog post my first thought was that I would love to do exactly this. I'm working at a startup right now but I'm so bored of the day-to-day and really enjoy architecture/performance tasks. I think I'm going to give consulting a try after I vest a little more stock :)
