It's either religion or Advertising

I am a Digital/Web Designer who has been working in advertising companies for a little more than 5 1/2 yrs now. In March 2002 I became Muslim. Since then it has become almost impossible to find a job within the advertising industry which would protect me from working on gambling, alcohol or something similar which would compromise my beliefs.

I've realised, if there are any morally positive advertising companies around, I haven't found one. Now I am on the verge of quitting my job just to save myself the anguish of having to design yet another alcohol related product. Is there any light out there?
