Build Website for a single product purchase

Looking to build a whole new online single product being sold simple website with very easy checkout! I already have a site built thru networksolutions take a look that i want to build a new whole platform with a very professional homepage with the main product featured and a buy it now button/ with cart .. The platform has to have an offline checkout as we are not prepaired yet to go to online trasnsactions.. It's a new product so the home page has to look and feel like a hot new product..... I have pictures we can use and i do have ideas how i want the home page! It's a pretty easy project but i want it to look very rich and impulsive to purchase the product..We will then transfer domain name to new platform. check out the website: [login to view URL] thats the product we are selling!
