528549 create website duplicate in format an functionality also SEO

I found a site which has the look and feel that I need for my business. I will need the ability to control from the admin, uploading, text, photos, add to blog, and banners. Also the site should capture email addresses for mailing list etc... I found a website which has all of these components I am looking for so I would like to duplicated design and functionality of the complete site, with some graphic changes to fit with my companies identity. The site is paulfrasercollectibles.com. I am not sure what would be the easiest platform to use to have this complete functionality including, the shopping cart which I will leave to your opinion and design capabilities.
