It doesn't match all of your wants, but you should consider living in the inner city of a large metropolitan area and working for tech companies there. In Los Angeles, a talented dev/arch with devops can make $185,000/yr with benefits. Another possibility would be turning into a migrant fruit-picker, stick your stuff in a storage facility and follow the contracts around the country, looking for the $200/hr gigs.

Do all of the above, then retire early and spend your time developing your own client list at your own pace at home, working 0 to 10 hours per week.
