If you sell something, it's half price.
Also, does anyone have a preference as to which setting you want this in? Forgotten Reams, Eberron, Greyhawk, Dragonlance? I personally know Forgotten Realms and Dragonlance pretty well. I've always liked the Dragonlance Magic system, forcing wizards to choose between white, red (neutral) and black, but the simplest would be Forgotten realms, as you could pretty much just do whatever. Thoughts?
