What were the jobs that George had his kids pursue outside the house and how did he promote them?

Growing up, Kelly and her brothers all had household chores for which they were paid. George decided that the boys needed to branch out and showed them a bright green t-shirt that said "Corrigan Cutters" in bold white lettering that he had made for them. It was time to bring in money from outside sources. The boys were less than thrilled. Kelly thought she had escaped George's latest sales innovation but she was wrong. He pulled out another t-shirt that said, "Corrigan Cleaners." Kelly could make some money cleaning houses. Kelly was relieved when the cleaning business failed to take off. Booker got into it and in no time had saved $50.
