I am using the wpremix theme and would like it modified as per my mock up and using the template that is included with the theme that is widget ready. This means changing colours in the css for the fonts and nav bar, inserting icons next to the items in the blogroll as per the attached. Giving the overall theme templates a blue/green colour scheme as attached. Making a little advertising box as per the attached mock up and generally making the theme pretty. The colour scheme must be changed throughout the templates not just the home page. You may have to make another template that has two sidebars in order to complete this task.
This should be an easy job for a wordpress/css wizz.
Let me know if you have any questions.
