Venturing into the World of Graphics

So, I started up a graphics thread yesterday, and luckily people seem to like what I do :) Currently I've been getting requests at a good pace, so hopefully either: a) It'll stay like this, b) Someone will join my graphics team, or c) People will be patient in receiving their graphics. How long do normal graphics artists take to deliver their work? I always aim to have it done either on the day or early the next day, but that's probably a little ambitious. Ah, I'm new to this, what the hell :)
