For Erie Canalway signs, try The Canal Corporation.
Phone for Canal Trail Information: 518-449-6038
I have found the Canal Corp very open to discussion, information.
If you want an Empire State Trail sign -- not sure about that. I'd try I Love NY [800 CALL NYS · firstname.lastname@example.org] as a starting place.
So, Mark, post a trip report about your ride here! Let us know how it went.
