Now that question tells me you don't live too far from me (maybe). Did you do the Festival of the Tree (or Treefest as it is now) over the August Bank Holiday?
They sell green wood, or at least mostly green, some part seasoned if it's been down a while, certainly not fully seasoned.
It's also mostly in slabs, furniture making thickness (1" or 2"). Some branch wood and thick shrub woods in the round. Prices aren't to bad. If your lucky they will be cutting to order and you can get a thicker slab cut, but it's the whole slab you have to take. Or have someone to share with.
So you'll need to think about storage and drying.
However, it's always worth a visit to see what they've got, sometimes some nice Box (I got a big 4' x 4" stem for £10).
