This is what I would have done if I would have been in your place. Instead of building the website I would have build a business around the products I sell. May be a blog where you can write your own articles which can get SEOed and rank higher.
Just article submissions and other can get your on top for keywords but you never know if you will make sale out of them or not. Have you done the keyword research as well as PPC marketing to see if keywords you are targeting convert or not?
