Folks look for "deals" on eBay (where deals tend to be few and far-between these days!) and craigslist. But those venues can involve waiting... and waiting... and if you need money now, I'd suggest posting the canoe for sale in several places, including the classifieds on this website.
I once had a very pretty, completely restored canoe that I had to sell for financial reasons, and my guess is your situation may be similar. My canoe sold through Antique Boat America, which took 10%, so when listing it I adjusted what I wanted a bit upward to compensate for that. I have no interest in that company and my experience with them happened a few years ago. My canoe sold fairly quickly... within a month, as I recall. The company arranged transportation and a fellow came to our house with a huge truck... he was traveling all over, picking up canoes to take East. We put him up for the night, and had an interesting visit. Anyway, it was a positive experience, except for regretting that I had to sell the prettiest canoe I've ever owned and wishing I still had it!
