Basic Design of Yahoo Store

I have an ecommerce website that I would like to have moved (redesigned) over to a Yahoo Store.? We sell physical products.? I have the design in mind -- it is nothing fancy. Please have Yahoo Store experience ## Deliverables Let me know what a cost might be .... I was thinking $100 But, I don't know if that is realistic since I've not done this before. If it is more than that -- than maybe you can just setup the template and I can add the products, images and so forth.? I need a good Nav bar - static if possible -- good header and footer setup --- I tried to work with the Store Editor and did not have much luck. Let me know if you have any questions. Thanks. Richard
