Design of appcelerator titanium application

We have prototype of appcelerator titanium application. It has two screens with lists, one item view screen and one web view screen. We need to design it so it looks nice and sleek. This includes replacing all standard appcelerator titanium images, changing of all three views and patching of css for html files displayed in web view (these are web forms with some input and output fields). If you read this, include word "Amber" in your bid.
