The team sale
When sports franchises approach sponsors, they bring an entire sales team. The point is not to overwhelm, but to show deep commitment from the organization, and to be able to provide ideas, answers and suggestions immediately to the client, while they're in "the mode."

If you have a quality lead, ask for a meeting with a few members of your team: maybe your Digital Manager, a Promotion Director, or Programming. Your client will be impressed that they are worthy of everyone's time, and the ideas and answers will be plentiful.
