yes, use Adams Co. nursery in Pa? or NY?
https://www.acnursery.com/ you can literally order anything from them with the root stock and scion you want. all you have to do is set up an account that you are a marketer... selling the fruit you are growing. we started using them after visiting with a friend who is a LARGE grower. he told us to try them... thats who they use. they order a year or two in advance as they grow thousands of fruit trees. We ordered ours (which took a year) so we could get the root stock and scion we wanted. they grafted specifically for us.
