In my area (Connecticut) there are a lot of various "land trusts" as well as municipal conservation land.
I would think these would be a prime pool of potential customers. Of course many of them may be interested in the combination of a professional forester who plans the cut, combined with a low-impact logger. If you talk to them and find out if they're already using a certain forester that would probably be a good person to talk to.
Many of these are very sensitive to "looks." Back in 1991 I worked for the town cutting trails on our first bit of conservation land.
Ten years later...over which time I had nothing to do with the property other then occasionally walking or riding it for my own pleasure the town had parts logged.
And I had multiple people complaining to ME. If I was getting an earful when all I had done was work there one summer in college, I can just imagine what the town politicos were getting
(One of our local land trusts is even sponsored by the local forest landowners association that encourages good timber and firewood practices)
And even if you don't get business with the land trusts, if you can make a good impression to their boards / leadership I'd suspect a lot of them are the types of folks who would be interested in low-impact on their own personal properties.
