Pawpaw pollen exchange or purchase

Looking to cross-pollinate your pawpaw tree? I have a mature, healthy pawpaw tree and want to swap or purchase pollen. I have a NC-1 with many blossoms but no way to cross pollinate. I'm located in Toronto. The picture was taken May 14th. If your trees are about to bloom and you want to boost your harvest, let's trade or I can purchase ! Please send a message with your variety and location.
