Hi Jeremia, I'm sure selling such a large collection will be difficult. What city are you located in? You could try reaching out to a local LUG to see if they might want to buy it as a group. I'm in Toronto, with ToroLUG.
I may be interested in your collection but first want to find out what part of Canada you are located in. The reason I ask is that I am from Wisconsin and if it is near the border it would make a purchase much more of a possibility.
