Free Garden Catalogs

Looking for a free wordpress theme to use for an on-line catalog.? I am creating a website to showcase handmade jewelry. there is no need for any e-commerce since i will not be listing any prices, it's merely to be showcased in a "wholesale catalog" type of feel but have the navigation that people used to shopping on-line are accustomed to. if anyone can point me in the direction of a free or LOW COST WP-Theme, something that i can modify slightly to suit the logo/branding.. i'd be thankful.
