Convert website to CS Cart with enhancements

Hi I want to get a quote on transferring our website [login to view URL] from shopperpress to cs-cart. As part of this we want to "refresh"the site to make it more user friendly and easier to order. We also require the ability to change the banners easily and on a regular basis within cs-cart and are looking at the add-ons available to do this. A part of this is to also improve the sites on-page seo. Also looking at add-ons for this as well. We have used CS-Cart in the past and have yet to find another cart that is so versatile. There is not very many products, and the current page works ok, but could do with a facelift. In the future we may expand the site to allow for the potential for distributors. This isn't essential to have functioning now, but more so we want to know that capability is available in the future. Social media is very important to the visibility of this business and we have a very active facebook page. Ensuring facebook/twitter ties back to the website is very important and any improvements how this can be incorporated in the website will be considered. Thx
