I am trying to help my husband come up with an idea to start his own business. Right now he works in retail and he specializes in getting people throughout the store to sign up for a store credit card. He is really, I mean really good at it. He is #1 in his district every month and nobody seems to be able to figure out how he does it. I am wondering if he could start a company that goes around doing training for stores who have their own credit cards. I don't really know where to begin looking into this. Does this sound like a good idea or not or is there something else he could do that would tie into this skill?
