Developer needed for Video App Demo (Tablet)

Good day to you all and thanks for reading! I am looking for a developer to help me develop a small video app. It will only be a demo to show off to a client, but it is quite a complex design. It is a paid job and in return I am looking for a professional job. The developer could end up working full time on a full blown project at the end of it all. It is basically an app that lets you analyse video clips - this will be for tablet devices (Android, iPad at first) but looking to expand to PC as well, that way you can edit and share on multiple devices. You can analyse the video in different ways - but for the demo this will be limited and you will only need to develop the app around one video. I have a Powerpoint presentation ready on what I am looking for, plus I can explain the various points in a brief. The developer must have Skype and be able to start right away. I will also need an update everyday if possible. Only apply if you have the necessary skills! Please provide samples of previous work.
