I don't know of many mills that will do that. Our Marketing boards do publish mill specs and prices though, and it's good to call the Mill in your case for latest prices.
Here is a scanned copy of the prices from the local Forest Products Marketing Board. The prices quoted are worked out for our Board because we have two wood yards that a local trucker hauls from, to Columbia. If you deliver your own the prices are a bit higher, so much a thousand for delivery. They have been good to deal with and if it weren't for Columbia then the wood would end up in pulpwood, or sawlogs. Prices have fallen in the last 2-3 years like anywhere you sell wood.
