oscommerce modifications

We have a new oscommerce store using a template from template monster. We require several customizations prior to going live. Mainly installing plugins, there may be some custom programming required also. 1. We require a blank home page, should consist of the header, footer, and left hand side navigation. This will be a static HTML page, updated by our designer, so please keep as a separate file from the programming logic. We will provide a Photoshop mock-up, will be straight forward, bit of text and some images, we will need this to be coded up and put in place. 2. Install this plugin (price break) and make sure it works and displays correctly on the front end. [login to view URL],1242 3. Install SEO friendly URLs plugin 4. We need to charge a packaging fee, this fee is applied to every order. Might be some custom programming here? Maybe it could be a product that is automatically assigned to the cart when checking out? 5. We need functionality to add category descriptions. Entered through the admin tool, and displayed at the top of pages when viewing by category. 6. Product attributes are not displaying properly when customers are selecting products. The select box only displays 10, even though 12 are set up in the admin area. Eg. [login to view URL] 7. Question to be answered, are there any plugins that can automatically convert languages.
