Volsuion Clothing Store Design and Setup

Hello there, We have volusion ecommerce web site (clothing: men and kids) and we would like it to be different than other ecommerce websites and templates. What we are looking to have on our web site ([login to view URL]): 1) Storefront and Categories: We currently use volusion template. We would like to have professional, simple and tidy look on our storefront. Our customers should be able to navigate easily as much as possible. Page loading time must be at its minimal. We would like to have light color combinations. We have logo but will consider new logo designs as well. We do not want gliding picture messages on the front. We want to give one message on our storefront. Right now it says Grand Opening as volusion setted it up. Besides our main message we want to show our promotional items on our store front as well as deal of the day or hour. Our categories might need rearranging or some add ons. Newsletter subscription, RSS feeds, Social connections will stay on our main page. We will have 4 main categories on top navigation menu. Men's, Kids, Special Offers, Clearance. These main categories will have their own subcategories under subcategories. We would like these sub categories to be displayed nicely on left hand side of the web site. NOT as its displayed on volusion provided templates. 2) Filtering. Along with the subcategories, we would like our customers to be able to filter products for their needs on the left hand side of the web site as well. We want our customers to be able to filter products by their; Category, Brand, Size, Color and Price. NOT as drop-down filtering on Volusion! For example: Lets say customer is in our site and clicks on Men's Clothing. On the next page's left hand side he/she should be able to select subcategory of Men's Clothing (subcategories: coats and jackets, suit separates, pants, shirts and etc) along with the brand, size, color and price. Keep in mind size schemes might vary by sub category. Pants and Suits won't be using same size schemes nor will be the Kids. We prefer check box style for filtering so they can be able to select more than one option if they like. [login to view URL] could be an example of what we want it to look like.. 3. We sell on Ebay as well and we would like to have template for our ebay and facebook store which will be identical / similar to our web site. 4. SEO and Traffic building will be needed for the web site.
