Simple Demo Trading App (Virtual only) for Android

I'm looking for an expert Android developer to create an App that trades virtually against a few API prices. Brief: The user will start with a virtual amount of money in their account, and they will just trade a few currencies virtually within the app. Database on web server will store their virtual details and virtual amounts. Users can also follow other users and watch their trades. Users will have the normal functions of login, check profile, change simple settings. The UI and navigation styles should be at least to the Honeycomb standard. It shall be clean, simple and user-friendly. Compatible with Android 2.2+. Google analytics tracking. - - - All code and intellectual property shall belong to the employer. I will provide necessary graphics and logos. More details/specifications will be provided at later stage. I'm now looking for a reliable Android developer who I can work with on long term basis. Please make a bid below $175 AUD. Non-generic proposals will be highly favoured over generic proposals. Look forward to working with you. Cheers
