Hi Judy, I'm just back online after island hopping for the last few weeks so just seeing this now. I'm guessing you've gotten this covered, but if not and for what it's worth, a friend recently used Guy Faulkenheimer of Coast Marine Service out of Albany and found him very thorough and credible. While a couple of hours from Champlain he might be worth considering if you're still in need given the limited resources further north.
