New Client...wants it all

Hello to all once again...
After being in business for 3 years and doing everything possible for clients I have the opportunity to take on my first big client. I have joined with another company and we offer everything to meet the advertising needs of people in our area. I talked with the owner of the business and he heard "how great our presentation was and is looking forward to meeting with us." He asked me though if we handle everything. What he wants and i am confused is that we make money off of how well his commercials air on TV? Not sure if that is what he meant and he was talking about rating numbers and such. Let's face it I am confused about this but he wants to call up and say I need a spot about this product done and to air by this date. And that is all he really wants to do. He doesn't want people selling coming to his stores he wants to refer them to us and handle it. Has anyone done something like this before. I know many may not be an ad agency type and I don't like to call us that so much. We are more a group. But any guidance would be totally appreciated! Please help.

Thanks soooo much in advance;
