joomla 3.0.2 Css modification on Wright framework

Hello! I need to slightly modify the Wright Framework's Css template on my joomla 3.0.2 site. I need some customizations of the css: background image, 960 width, add a style to an acymailing module. I will not open my server, I just need the final css file with instructions. I use 3.0.2 joomla on php5 and Mysql as usual. The Wright framework is provided by Joomlashack. DON'T APPLY IF - you do not work within these specs. - with a general type of offer, I will discard it right away. - you think it will take you more than 2 hours. - you can not set up a replicate a blank joomla 3.0.2 on the Wright framework on your servers to work on my project. - you want to be pay otherwise than by the freelancer policies. We will use Skype and Teamviewer to communicate. I will need you to modify theses css on other projects (15) as well eventually. Thanks.
