Custom Skins for Spark Flex project components

Custom skins based on a color scheme has to be designed for all components used in a Flex project. Almost all core components are in the project like TextInput, TextArea, Tree, List, DataGrid, TitleWindow, etc etc. We will also need skins for custom components like a button with just an Icon in it, a custom Spark Tree, a custom text input with a search button built in, and for items like custom widgets that were created for the project. We prefer skins with FXG graphics wherever possible and only use images when needed. This is important as we would like to stay away from using too many images in skins. The end result should be actionscript skin classes that can be plugged into the project with very little effort using a stylesheet. If the deliverable is an actual flex project with a style sheet and illustrating all the components that would be ideal. A screen capture of the application is attached. There is a new icon set being designed for the new skins and they are most two tone icons that will be a very clean look as opposed to the various colored icons we have in the current application.
