Stapleford offer a good rate on their large fleet of C152s (£65) if you put some money up front. You could try and lease a C152 or tomahawk or similar. They are quite hard to find but there are are some about. Rough price guide would be about £30- £35 per hour - you would pay fuel, parking, landing fees etc. Worth a thought.
800m of tarmac - short?!!! Not really. Shobdon is very nice though.
