We need an app developed for iPhone/Android/Blackberry in which our corporate team building clients can participate in a scavenger hunt. Details in the attached files. Looking forward to your proposal. ------------------------------------------ Added 20 JUL 2012, 16:28 PM EDT Here are a few more details. 1. We just added a balsamiq mockup of the UI. 2. We do not have a pre-existing API/back end. This would need to be designed. And we do not have a host server. 3. The selected contractor would also design the UI, suggest colours, icons, etc. You would have access to our logo for the main login page. Desired Skills: Android iPhone BlackBerry Keywords: Mobile Applications, iPhone, Android, BlackBerry
