Fresh hardwood logs (Shirley CR0)

I'm looking for fresh hardwood logs to try and grow mushrooms in the shade of our back garden. I would like freshly cut (in the last 4-6 weeks) logs from healthy hardwood trees. Ideal are oak, maple, birch, ash, alder and beech with a diameter of 8 - 20 cm and length up to 1m.
Many thanks for reading this post.
