I need some help from a wordpress ninja if you’re out there.

I’m using a woo theme for Children’s Ministry Online. Unfortunately, my sidebar is slightly too narrow for something I want to do. Literally, I need the sidebar to be about 4-6 pixels wider. Unfortunately it’s not as easy as just changing some numbers. In addition to some code changes, it also requires some changes to the background image (says the Woo Themes support forum). So, I’m getting some quotes from some affiliated Woo Theme Customization workers tomorrow. Do you or anyone you know have the competency to make the modifications I need? Feel free to let me know my contacting me from my contact page.
