Lol!
As in, hackberry tree?
Celtis occidentalis?
I can certainly help with that!
I'm rather surprised you can't find them locally...
I also have some sugar berry around here, a very close relative of hackberry.
I'm not sure what other plants I could provide for you, can you be more specific?
Do you only want natives? Trees?
What do you hope to harbor with the plants you seek?
I honestly didn't know that hackberry was of much significance to wildlife... Time to get to googling!
I'd be very happy to help, but the more I know, the more I can help!
You can tree me if you like, but a public conversation might benefit your cause more.
