How to attract sponsors
Develop a budget for your event.
Before you begin the search for sponsors, you should get an estimate of how much your event will cost. Determine how expensive it will be to do things like rent a venue, pay for advertising, cater food, hire security, and print t-shirts.
Once you have a grasp on how much this will cost, you will have a better idea of what you need and what to ask for from sponsors. Work with an accountant or your finance department to determine how much your event might cost.
