Is that steady work or well-paying intermittent? I get the impression @jameson_nagle may be looking for some degree of financial security (mybapologies if that is not actually part of your criteria, Jameson).
E.g. We have state parks that do controlled maintenance burns, but they have very small and specific windows when they can be scheduled, and those can be disrupted easily by many factors (wind, drought, availability of local fire departments for backup, availability of trained fire starters, etc). It is similar, because there is a commercial component to these parks (entrance fees, cabin & equipment rental, licensing, parking permits, etc).
