The sign says that they do not do business with Jill Kelly Productions or with Sin City and that if either of these companies bounce a check to you, World Modeling cannot help. Oddly enough Extreme is not on this list and word has it that they are the worst in the industry to bounce checks to talent, producers, directors, advertisers, duplicators, printers and even employees. According to one of my sources World modeling did apply pressure after 3 of Extremes checks to her bounced and Extreme finally made good.
