Not sure what part of WI you are in, but there is Van's Pines in SW MI. They grow conifers in Jiffy pots which are easy to plant. I got a couple hundred from them in 2012 and they were very nice trees and nice people. Otherwise, if you are worried about shipping costs, NCR and maybe Itasca will pull them from the pots and wrap the roots in plastic. Makes shipping very reasonable.
