Startup Idea : I need it here app

The idea of this app is that mobile users use their current location and they specify what business is needed in that location,for example a store or a hotel that is specialised for a community, a bakery ,a clinic, or anything.Suppose some one puts up an idea like that other users in the area vote up the idea.So say i need an indian restaurant in my area and i get around 500 votes,that shows the feaibility of opening a restaurant in that area.This data is shown to potential businessmen who are looking to open an indian restaurant and then they can choose a location for that.Similarly if a public utility is missing in an area,the amount of votes for that idea can be shown to the authorities for installing that utility in that area.This app can gather requirements(demand) for a location from multiple users and then show it to people who can fulfill that ideas(suppliers) thus helping business
