Associations and Advertising Agencies as Partners in Your Event
Another method is to collaborate with associations and organizations over a win-win game.
To collaborate with organizations, bring them some benefits. For example, give them a booth or have an interview with the head of that organization and publish it in the fair's magazine so the organization can introduce its members, and most importantly, they can announce that they are officially collaborating with your event, which is an approval for the event and makes the subsidiaries a source of income for you.
When the subsidiaries of an organization witness the sincerity of that organization in collaborating with the event organizer, the chance of them participating in the event will increase. The pertinent organization provides you with services in proportion to the resources you offer them. One of these services is the credit they bring for you by their support. The organization in question is not supposed to be a partner in the entire event; it only participates in the process of holding the event in general. Don't forget that a long-term collaboration with such organizations is in the favor of both parties.
Collaborate with advertising agencies decidedly. Suppose every advertising agency has a major customer. In that case, the same customer may bring you some huge profit and it will be enough for you to have one single customer! First, target those advertising companies which are related to various organizations and companies of your event's target market.
You can also give a free booth to the trade union pertinent to your event, and talk to charities and give them free booths to support them.
Another method is to barter. I gave a place to a restaurant in an event, and that restaurant kept preparing food for our colleagues for a while. Keep that in mind that the event does not reoccur. Therefore, get the most out of the place on that day.
In the modern world of business, any kind of connection comes handy for you one day.
