I reckon if you give the good folk a reasonable expectation of what you're looking to achieve price wise then you'll stand a better chance for these beauts....

I have a vested interest in your success as I own a framed St Giles which adorns my hall and looks great - provokes much more commentary than other stuff by some bloke Banksy...
