543902 CMS for distribution

Would like a CMS that can be redistributed and is easy to use. It would need to be rebranded easily. The design should be attractive and make good use of imagery. Should have categories for pages. Should have subcategories also. Links on main site should have categories as main links with subcategories showing on hovering over main category links. Page categories will display on top. Should have categories for products. Should have product subcategories also. Links on main site should have categories as main links with subcategories showing on hovering over main category links. Product categories will display on left side. - Product pages in admin will allow for addition of image (will resize automatically) and description. There will not be an option to buy online (not an online store) Structure should be header, 3 columns and footer, but must not look boring. Please reply with bids and show samples of any existing CMS that might suit.
