NYC travel guide

This is Miami winter music conference application that is already exisiting for the iphone: needs to be ported to android and add featues. The new app will feature new york city features. the former app was about the winer music conference (a guide book with an index of locations and written info) the new app is the same, but for Times Square in NYC, one app for iphone, 1 android Now to adding the features that dont exist, I have the map and map detail code, as well as the info "coverflow" browser done in another app that we can port" as well as the web view, so its fairly far along but does need new code. features to add: a ticker on the front page, a countdown clock, a photo submission tool (with in app purchase), and a message builder tool we'll need to port the art, rebuild the ui, and start from base must handle 150,000+ concurrent users (meaning their server handshakes / fallback code need to be good) I have the map and map detail code, as well as the info "coverflow" browser done in another app that we can port also have the xib files being built as we speak Price should not be so high since it is not entirely from scratch, and will take less time to complete than creating a new app and design. Must be a company to do this, must have good feedback, payment in freelancer milestone only. Additional info has been attached.
