Complete website and ecommerce setup

We are creating an info product and we need an online ecommerce site. It needs to give away a free report on landing page and contain a link to main page as well on that initial page. Customers will pay for various info products that they can then download. We'd like this to be turnkey meaning you design with us, help setup an FTP client if needed, and then upload to a host with username and password then transfer account to us. We'll help select domain names purchased etc. willing to establish a long term relationship with you as webmaster.
