I would like to hire an App Developer

I am very interested in Stock Market and I think that it is missing a way to look at this fantastic world: price distribution. My project, therefore, is to create and distribuite an app that elaborates and visualizes price concentrations for a given stock/currency (or anything that can be visualized in the iPhone Stock App). A very good example of this application coud be found at: [login to view URL] This app (Stock-magnet) is no more available. The biggest limit of this old app was that it was not possible to visualize stock from all the world market, the application was limited to the USA, France and Germany markets, and only stock (not currencies). I kindly request: 1) a quote to develop this app; 2) a quote for updating this app twice per year for 5 years. Thanks Giuseppe
