Customize WordPress Theme / New Header

Hi, I am looking for someone to finish a design/customize job on a WordPress theme (Origami). The main tasks are: * Some tweaks to the colors used (one change done was the option of a white-on-dark design in addition to the dark-on-white default, which can be switched by javascript without forcing the page to reload) for both versions. In both cases I am not 100% happy with specific colors used. * LiveSearch as used in the style is broken -- this might be solvable through the use of a separate LS plugin. * LiveCommentPreview (plugin of your choice, as long as it works) needs to be added. * The header needs to be completely redone to incorporate our logo. I am not looking for anything fancy -- just the existing logo on a plain background. The small icons in the very top left corner (check mark and X) which were meant to be used for another feature but now allow to switch between both color versions need also to be done new since they don't reflect their action anymore. A screenshot of the style is attached -- a test version of the site can be found at: [login to view URL] (Note to GAF: no contact information!) A screenshot of an early draft of the intended header (sadlynodark) is also included. Thank you!
