3dcart design and major SEO maximizing

I own the website [login to view URL] that currently has a wpecommerce built store. I have one product in particular that I believe could be ranked in the top 2 of google for the keyword term "berberine". Right now I am in the top 10 but slowly moving down with my current store. I bought the domain name [login to view URL] to make another store that will easily rank at the top. The other reason I want a new store is for better functionality. I would like a customer to go to the page and want to buy it now and be able to easily purchase it. My site right now has troubles with purchasing. So here is what I want: 1. A 3d cart driven site put on my domain [login to view URL] with a design that is very similar to the one I have at [login to view URL] 2. I NEED my product Glycosolve to rank preferably number 1 in google when you search "berberine" 3. I want the cart to be extremely easy for the customer to checkout 4. It would be nice if the person who takes on this project is a copywriter 5. I want 3dcarts autoship function in this store Other things that will be considered for whoever gets this project is if they know of other ways to promote my health supplements - possibly through press releases, social media etc. Thanks
