Where to get a wooden board cut?

[green_avocado]

I have a wooden board that I need to cut. Nothing fancy, a straight cut to make it a bit shorter on one end. 

B&Q offers this service, the closest location that has it is Sydenham.

Does anyone know anywhere local where I could get this done?

Many thanks!

North Cross Road, behind the Palmerston, there’s a carpentry workshop? Not sure what they’re called.
