Yahoo Small Business Shop Help

I need someone to answer questions when I have them about a Yahoo shop. These include items like "Where do I upload a custom CSS" "How do I move a module from one column to another" "How do I change the behavior of a menu?" "Does this CSS property work in Yahoo Store?" You will not have access to the Yahoo store. Project is hourly. 1. ENGLISH is extremely important 2. MUST understand and know how to use the Yahoo Small Business WYSIWYG - both current and past editions If you do not meet those requirements, do not apply.
