Where to Buy Chestnut Seeds

I’m looking for an online source to buy cold stratified Chestnut seeds. I’m looking for American Chestnut variety or an American Chestnut hybrid variety that are blight resistant.  I’m also open to buying small saplings/ small trees, but preferably the seeds.

Burnt Ridge Nursery often has chestnut seeds and plants for sale, but I'm not sure if they have what you want right now:

If you decide to contact them, please let us know if they have any chestnut seeds available now, or if they will be taking orders in August, since I'm thinking about getting some chestnut seeds from them myself.
Thank you and good luck!

This farm sells American chestnuts bred for blight resistance but not during the growing season. You may want to look into them this fall.

There is a chestnut land trust in Maryland that you can hike through. Surely there are ones laying on the ground and probably sprouting right now
