I want a unique t-shirt website built.

I need a commerce site with back in database for inventory and mailing etc, I guess this is known as a manageable back office for the inventory of prodcuts .... this will be a christian based t-shirt website. I want it to be unique and have the ability to add more pages, and manage the site ... My goal is to make available unique t-shirt design with positive sayings on the tshirt. I already have several t-shirt graphics that are ready to go ... will always created more new designs ... so i want to be able to post on the main page different focused t-shirts. If you could go to wordwalk.us ... you will see an example of how want the top of the site to look so that we can have a rolling large banner that features people wearing our procuct .. and there will be four categories that you will select that will bring you to different t-shirts that the customer can order online and its shipped to them. I also at the bottom of the home page want to have the opportunity to highlight 2-3 of the shirts on the home page .. and also a location have text about upcoming events and special subjects etc ... I already have the company logo designed .. the website name is: TRULINGO We also have a slogan that goes with the website name. I also already have the thumbnails for the different t-shirts that we will offer. open to the type of development .. prefer ecommerce or wordpress etc.
