Redesign ecommerce site using Yahoo Store and X-Cart

I am in the process of upgrading my ecommerce site. The successful bidder must have proven knowledge of both Yahoo Store and X-Cart shopping cart software as well as SEO experience. Existing site at saucycontessa.com. Please do NOT bid if you do not have a portfolio with similar completed projects. I will not respond to private messages that ask me to go through an extensive portfolio and don't tell me why I should consider you as a successful bidder. Please be prepared to tell me what you would do to make the site better in simple terms. Bidding should be at low - medium range of budget to be considered.
