Is it possible to get a job dealing cards without casino school?

Hi there, I've been considering pursuing a career dealing cards for quite some time. The only thing is if I don't have to go to school for it I don't want to. I've been dealing at a local place dealing poker and blackjack two nights a week for the past two years. It is a nonprofit charity gaming program and I think I'm pretty comparable to the dealers I've seen in casinos. What I'm really asking is will the casino give me the time of day to get an audition to deal there? I know I'm good, i know poker and blackjack, and i'm willing to learn other games, do I have a chance without the school?
