Apple, Peach, Plum and Cherry for grafting class

[TnTurkey]

Our Master Gardener Association is sponsoring a grafting class this March. We're looking for scions of apple, peach, plum and cherry.
We need a minimum of 120 pieces and will appreciate anything that the forum members can send us.
I've posted a list of varieties known to do well in our area (zone 6/7) on the scion list page, but will not be picky.
I have about a dozen apple and pear trees that will need pruning (also on the scion list), or will be happy to pay for shipping and handling.
Thanks much.
