Android app to post classified ads

I am looking for an Android app developer to build an application to post and browse local classified ads. Users need to be able to: -post their picture or ads -manage their listings -browsing by categories or location (province or state), -conduct local searches. -Respond to ads -build their favorite list -login via the app or via facebook connect -view third party mobile ads (e.g., mobile google ads and others) I will make the final payment once I have sucessfully registered the Android app in the Android Market.
