iOS/Android App developer

I am in need of someone to create an app for a small community whereby the following features would be required: - Social app where users register themselves with relevant details. - Admin authorises the user once satisfied details are true and correct - Admin can delete users or ban them. - App shows all registered users on a map - User gets an emergency panic button to press in case of emergency - App can alert other users of panics. - Users can talk to each other in a closed group similar to how Zello works (optional) - Paid app, either user pays or admin pays. - Admin can post updates to group - Users can log events in group - Rating ability to rate other users - Participation rankings for users who are active versus those who just consume I do not have a design so your bid should include that as well
