I voted Wxm, though if you don't win, why don't you just give it a bloody good go yourself mate?
When I moved here the garden was far far worse than yours, an overgrown death trap but I got stuck in and made a difference. We also started putting a few bob aside back then, small amounts and have now, three years later, laid a cracking patio area across the back. All in all i'm proud as punch and, apart from the patio, it cost feck all except effort...
Best of luck mate..
