Open Cart modification

We're in need of a good developer who have experience in OpenCart. Main menu modification (See main menu on [login to view URL]) We need the menu to look just like kjell.com. But with our current design. All the links can be static. It will mainly be CSS changes for you. Full width on the drop down menu and don't forget the little text area to the left in the sub menu. Live price update We need to make the price update when the user makes any attribute change. The product will have a base price and every time the user changes some attribute a new price calculation must be made. Quote button on product Next to the green buy button inside a product we need to have a button that sends the product with all the attributes and choices to a new function that creates a PDF. The user must have option to either email or save PDF file to computer. The design for the PDF will be provided by us. Quote button in cart Just like the quote button in a product we need the same function in the cart except all the products in the cart will be in the PDF file. The user must have option to either email or save PDF file to computer. The design for the PDF will be provided by us. Width x Height m2 Some of the products will have a base m2 price and the user will type in the width and the height of the product. Width times height = square meters. Square meters times base price = total price. This price is priority 1, then the user can make the other attribute changes just like before. But the square meter price must be calculated first and then the attributes based on that. It's important that we can activate and deactivate this on the products. We need this to be done as soon as possible! The faster the better!
