Wooden External Door for Shed (Great Sutton CH66)

Ideally a painted external door for a shed. Vertical boards is ideal. Window not required. Lock not required. Don't want it creosoted, just either bare wood or paint. Need to replace existing door. Ideally a substantial weight, not a flimsy construction. Size 187cm x 78cm. Can cut to size if need. I can collect.

Not chipboard please, I would like tongue and groove construction approx 3/4 inch thick.

Many thanks.
