Startup Idea : Advertise kickstarter projects in relevant stores

Kickstarter projects need backers. I would set up a computer screen in restaurants with kickstarter projects that appeal to local foodies, in boutiques with projects that appeal to moms, in skate shops with projects that appeal to skaters, in surf shops with projects that appeal to surfers, in video game stores, malls, etc. I would charge the project makers to be advertised in those stores, but if they don't make their goal, I give some money back as a pledge to their project and sell one of the items myself in the store. It could also be a way for businesses to publicize upcoming events or products that they want to produce.
