Great looking site!
How are you going to market it?
I know this suggestion goes against the Internet mentality of some, but I suggest you try driving some traffic to your site through some Direct Marketing test campaigns. You can purchase lists of people who have shown a track record of purchasing these types of items. DM them. Simple postcard campaign. Something that will get them to visit the site (after you made the corrections suggested by others above - which I agree with). Maybe a special deal, too.
Don`t forget basic marketing methods to drive traffic to your store - whether it is online or brick & mortar. Marketing is everything you do to bring the customer to the point of sale.

Don`t forget the basics. Build it and they will come is long gone.
