You should find out about doing freelance or something, my neighbor's son does freelance for music magazines (He's a plasterer by trade/day) such as Kerang etc.
He showed me some poster sized pics of the stuff he's done that he used for a gallery. I was quite suprised because he's taken pic's of Kirt Cobane, Bob Dylan, and tons of others.
He offered me the posters because they fill his parents garage up, but I've got no room for them either.
