Detroit Muscle - GoDaddy QSC CSS changes

Need to make some CSS changes to my GoDaddy QSC template. I have selected the "Shop - spotless" template/theme. I need someone to put the code in the "Advanced CSS" section so I can change the fonts. Need to change the sidebar fonts, Product heading fonts, etc. I want all the fonts to be Arial. I want the code in the Advanced CSS section to be labeled well enough so I can tell what font it's changing. I may need some other help as I continue. We could do an hourly rate not to exceep, or a fixed price. We sell 60's and 70's muscle car body restoration gaskets; [login to view URL] My literature theme is monochromatic and minimalist. I would like to keep my shopping cart minimalist/monochromatic also. You can download one of our pdf catalogs like the 70-74 E Body to see the product. James Fillmore Detroit Muscle Technologies
