I dont sell wholesale, I have a cut your own farm near Leroy, New York. If you are looking for bare root seedlings to start out with I would recommend Western Maine Nurseries...just google their name.
Hopefully you are aware of the work cycle and time required to grow Christmas trees. I have found it worth while but alot of people just think it is plant and wait. Spraying, mowing, herbicide and shearing are all yearly requirements for each and every tree.
Write back if you are serious
