I don't in your area. Like Pat suggested, you can go here:

Check NY and NJ and any other state close enough for a drive.
It's a long shot this one but here goes…
I stumbled upon a female who had (recently) purchased a tri boy 8 weeks old. She said the breeders name was Susan Kessall and she was from Cardiff, Wales.
I say 'recently' as this is what she said on her post on another forum. It was dated July 2008, so I am guessing the pups were born very late 2007 or Spring 2008.
Nobody I have spoken to in the breed in the UK has heard of Susan Kessall before so I wonder if she is yet another BYB in the UK.
I have not heard about her. Sorry. Maybe contact some UK breeders.
