You might try to hook up with someone on the ADKforum.com board also.
12 Years ago when I was doing the NLP, I called the local Lake Placid Chamber of Commerce and Post Office and asked them if they knew of any retired person who wouldn't mind picking my car up at the trailhead and spotting it at the terminus for a small fee of $25-$35. I got a few names of folks, and it probably would have wored well, but I ended up having my wife drop me instead.
I did the same thing when I backpacked across Joshua Tree in '96. and that worked out well. 'Course I paid $50 then because there isn't much out there in the desert. and it is a lot of driving to shuttle a car to the other end.
