Build a Website for my new company

I am wanting to get an online presence for my Christian T-shirt business on which to both market my shirts and hopefully also handle the sales transactions for my shirts. I have about 15 of the designs already completed and will have a total of 22 done in about a week. I would like to be able to display all of them on my site along with some written explanation of what I am trying to accomplish with them. I know very little about social media but have seen how it can really drive and generate business, so I am looking for a very eye appealing and creative site that draws people in from the home page to consider what we have to offer. In theory, once a customer selects one of the sayings, they will then select one of three colored shirts and pick one of 3-4 sizes, pay for the shirts and email sent to my box with the order and their name and address and payment to my account. It all sounds so simple! Basically, I am trying to share the Word of God, phrases directly from the Bible, that convey a particular sentiment or thought from scripture that may need to be explained or expounded on by the wearer of the shirts.
