Social Media Campaign

Read this: http://moringausa.com/moringa-college-craze.htm. I'd like you to design and carry out a social media campaign in order to sell my product to college students. I'd like you to give me the smallest project that will create some sales. Then I'll go bigger. Currently I have zero social media exposure so I'd like to start small and expand from there. I'd like you to give me a total cost for this project, the amount of time it will take, and the length of time it will last. Thanks!
