Is there a nursery in the Huntsville area that has both male and female hollies? Does Bennett Nursery carry them and are they labeled?
I would think that Bennetts would have a good selection. Most of their stock is labeled well. There's also the Catbird Seat. I've not been to Huntsville Wholesale Nursery on Leeman Ferry, but have heard that it is pretty good. I don't think that they have educated staff there, though.
You should have in mind the kind of variety you want.
I planted 90 needlepoint hollies in a hedge this last year at my home in NC.
While searching for a good holly nursery, I came across this URL for a wholesale nursery in Tanner, AL (just south of Athens.) You might try and see if they'll cut you a deal.
