Well with those specs i can tell you right now you won't be finding one as cheap as 500 quid!!
That actually sounds more like a custom order, you sound like a man who knows what he wants, and i think a custom would suit you well since you have the cash for one.
Also i can't think of any normal guitars with all those specs. If you took away the Ebony board then there would be plenty e.g. for superstrats - Ibanez, Jackson etc.
HOLD UP!!
I just remembered one which fits you perfectly.
