CollegeCart

I am looking to create a website called CollegeCart. The website will specialize in online shopping capabilities that will benefit college students. I have a rough idea of what I would like the design of the site to look like, but I am open to any suggestions. The content for the website is already ready and available, and I am looking for someone with experience in creating and successfully launching an online store. The website must also be integrated with a payment gateway and have user registration/login capabilities. If you have experience in this type of project, I would love to hear from you!
