We need a designer to create photoshop (psd) files from sketches for our mobile music application. The psd files will then be provided to a developer for coding purposes. We have our ideas for the designs but would like to receive input from the designer on effective color schemes and attractive user interfaces. We would like to work with the designer to create both a sleek and simple interface for the user. We require a designer that can commit signifcant time to this project because we have a short timeframe.
