An itinerary of the event. The event's budget. Biographical sketches of those putting on the event. Corporate sponsors want to know the people in charge are capable of pulling it off. What can you provide the sponsor for investing in your special event.
Sponsors sponsor for two reasons media exposure and community exposure.
If you don't have any money, the media would like you to bring in a sponsor who does. Lay out for the media, just as you would a corporate sponsor, what you need and what they are going to get from their involvement. If you more than deliver what you promise you will keep the media on your side. Unless you're spending a lot, you're getting a lot and you need to bend over backwards to make sure the media is happy. A dignitary's visit is newsworthy in itself, but combined with a special meeting or event, it can be an especially effective means of promoting your district or club.
