OS X xcode sample application

I'm a developer (C, C++, Java, scripting, php), but I'm totally new to xcode. I need to start very fast with an xcode 4.6 application for OS X, so I'm looking for a programmer which will send me the full project files/sourcecode. The application is very simple: The application will be used to search a file in a remote web database. The application can be composed of a search field on the top, and a result list on the bottom/rest of the window. When the user enters a text and press the search button, a http get will be sent to a PHP script I wrote. This script will return a json list of files. The application must show this list of returned files in the same way Finder shows a search result, so the user can directly open the file from the application or he/she can open the containing folder. Files are stored on a mounted network share in /Volumes/RemoteServer. I need the full project files and sources for this "skeleton" app.
