Canoe Tripping - Spanish River

This is a feeler to see if anyone would be interested in Spanish River trip.
There are several options how to run the river. See the following link for possible routes: http://www.spanishriveroutfitters.com/Routes.htm
The lower part of the river would take 3 days. The upper part should take about 7 days.
I'm pretty flexible in term of schedule (perhaps August/September) and the itineraries.
We might put in on the West branch of the river in Biscotasing or Snaker Creek. Both places can be reached by VIA Rail train from Cartier.
The take out then could be The Elbow or Agnew Lake.
