The company will be looking for other benefits from its association with your project. Be clear that you are asking for money. One of the most common mistakes made when approaching corporations for funding is not asking up-front for money, and explaining when and how it should be paid. In-kind sponsorships such as the offer of professional services or office space are sometimes easier to obtain than cash. Determine whether this type of donation will meet your needs.
Timing is everything.
Make sure your proposal is in before the budgets for the year are allocated. You must demonstrate in a business proposal format that your project meets the sponsor's needs. Provide a well-developed plan that delineates roles and responsibilities. Keep your sponsorship exclusive. One of the benefits of sponsorship should be a showcase for the partnering company.
