Flashy ecommerce site

I recently used two getafreelancer members to create a great looking ebay template (poonam75) and logo (keithone). Now I am looking for a spectacular looking ecommerce website where I can easily update pictures, product descriptions, prices etc. because my products change on a quarterly basis. I will be using a template that I will be purchasing from a third party. In otherwords, the person I hire will not have to develope a template for me. I simply want an existing template modified (pics, logo etc). I need a programmer to give me the ability to easily make constant updates to my online catalogue. I need it to make changes on the fly and I know very little html. In terms of look, the site will look somewhat similar to [login to view URL] or Also, I would like when my cursor goes over the picture, it shows a bigger picture balloon(similar to [login to view URL])--though its not vital. If you are an expert in ecommerce development and are very creative, please submit links to any ecommerce sites you have already developed and if possible, references.
