I have a news site with a decent traffic. It's all about hollywood only. I am planning to run a campaign and poll related to celebrities and local video shops. How can I get sponsors for these?
Find prospects, write a proposal, sell the sponsorship and fulfill the agreement after the sponsorship is sold.
Do you have any targeted sponsor? If you have then write a proposal for them. Then try to update then about their aspects & facilities and your aspects. If they think you are in right way then they will agreed to sponsor for your campaign. There, you must have to provide their Ads.
