Replying to Used Ski rails / boxes for sale in the Northeast?

Howdy NS. On a hunt for some backyard park features here. I'm the president of the Bates College SHRED club and we're hosting our annual open-format rail jam here on campus in a couple weeks. Been looking an FB marketplace/Craigslist for individuals or ski areas that may be selling old features but have had little luck. Our club does have a few shitty PVC rails but we've got a whole budget to blow and it would be sick to step it up this year with some real metal tubes/boxes etc. It's always a fun event with lights/music and a small crowd. Might be a longshot but if anyone has leads about purchasing or adopting old rails / boxes in the region it would be a huge plus for this event! We're located in Lewiston Maine, and we have a trailer for transport and can supplement pay in beer.
Cheers
