Hi,
I am interested in this project. I am an android application developer. I have worked previously with displaying location in google maps for android, searching locations in the map, sending and fetching data from webserver. Do you want this app to be a native android app or to be built using phonegap ? In case, you want it done in phonegap, I am afraid I will not be able to do that as I make only native android apps (written in java). Let me know. If you are available for a qucik chat right now, then message me here in freelancer.
Regards,
