I need a demo for a mobile app built quickly and professionally. The demo will consist of a few content screens with text and thumbnails, a home page with 3 buttons, a full screen image viewer and an image gallery. Content is minimal as it is only a demo product at the moment. The demo will need to be scalable for all devices, ie. iphone, ipad, htc wildfire, galaxy tablet and viewing on screen. This should be done using the css grid method for building scalable websites. Fee will be paid immediately following completion of the project and I expect to be kept updated on the progress.
