Website redesign, SEO, and Social Media Marketing.

There is a lot of work to be done. My website (www.venustars.com) is merely an online shopping cart that our clients (developed through Facebook and word of mouth) goes to, to purchase our products. I'm looking to redesign my website and apply SEO which will help in delivering organic traffic to the website. What is also required is to develop a stronger brand image and social media marketing for more organic traffic.
