The RC standard (and minimum, I believe) this year is 13,290 though, as Greg said. Nice bit of inflation there B-) I don't know about demonstrating, but Bath and Bristol are £23-£25/hr for maths tutorials at the least.
Well, as I did earn £30 at the weekend for a bit of computer worky stuff, I've just spent some of that on a train ticket. So! Legs broken and all that. :)
