What would be a fair price for the lumber from a good condition old barn and a corn crib?

I live on a farmstead in Central Illinois and have a large barn (43'x53'x36'high) that is in good shape except in a couple spots where the roof has gave in. I also have a solid corn crib (23.5'x36.5) that needs to be torn down. I have taken some of the lumber to two local lumberyards who identified it as cedar. I need to tear both down unfortunately because the roofs are getting bad and all my funds are going into restoring the farmhouse. I have had several people inquire about purchasing the lumber but am at a loss as what I should ask. Any suggestions or leads to interested buyers would be greatly appreciated. Thanks!
