Rutland is just down the road, I grew up in Manchester and now live in Dorset.
Getting a dealer license in VT is as easy as getting the collector's permit, just mail in a form for free and you get it. I do currently have my dealers license, so I can go to the plant pathologist and get an export certificate to be able to sell anywhere in the country.
I once looked into what it would take to send it overseas and that was complicated, but possible. I guess the hard part would be getting paid before shipping them out, there would probably be a trust issue with a new overseas buyer.
Keep me posted if you come upon someone paying good prices, between me and an uncle, we have around 10 pounds.
Very nice looking roots you posted, those are monsters, congrats.
