Modifications to OpenCart

Hello, I'm planning to use OpenCart to create an oline store for delivery of pizza. It will require the following add-ons or modifications to OpenCart: 1. CMS pages not using shop template page. (Affects:Admin & Front end) (Multi-Language) - Home pas has 3 content areas with one of them being a slider using 4 images/Text/Buttons - Other content pages have a 2 column layout content/sidebar - Sidebar may show Cart 2. Postal-code pop-up - upon entering specific page, stores customer postal code in cookie 3. Delivery Hours (Multi-Language) - Per day of week, there are 2 delivery periods/ day - Hours like 9h00-16h00, 19h00- 23h30 - Each day can be “off” like closed on Sunday - each day may have none, one or custom hours - Holydays managed by date (shop closed) - Add/Remove - using calendar 4. Postal Code Zones (Shipping Module) – (Multi-Language) - ADMIN – Manage Add/Edit/Delete Postal Code zones - Each zone has, Name, Cost in Euro, enabled :true/false, delivery time - ADMIN – Manage Add/Edit/Delete Postal codes (inside each zone) - At Check out and throughout the invoicing/order system – Postal Code adds a delivery charge as per Zone (ie : user enters postal code – price is changed for zone) - get from cookie if present at checkout 5. Delivery Date & Time (Multi-Language)- (As per #3 – Delivery Hours) - At checkout, dropdown used to choose delivery date (using calendar) - At checkout, dropdown used to choose delivery time - Time is now + delivery time as first entry + every ½ hour but not available during off hours - Do not display holydays and Hours/Days where delivery not possible - Manage holydays – add/remove/delete 6. Cross-sell at checkout Step#1 - (Multi-Language) - Display 3 products – One wine, one soft drink, one water – add button/pic - Also display More… (with preset categories – wines/drinks/water) - Clicking add – same animation as normal add to cart - Clicking More… takes client to that category page 7. Indicate step-of-checkout - (Multi-Language) - Use typical line and dots to indicate the checkout steps 8. Category text color in menu and on product list page (titles & css) - Add one extra field for category color (ie:#456789) 9. Change language via flag only (OpenCart) 10. Template/Theme (hard coded - not a installable theme needed) - HTML provided by me - Product page (list) - Home page (CMS) - Content page (CMS) - Header - Footer - Checkout – colors and buttons - My Account – colors & buttons 11. Checkout - Remove Country selector – lock to Spain 12. Checkout - Remove Region/State Seletor – lock to Barcelona 13. Checkout - Remove City Filed – hard-code to Barcelona 14. Checkout & Admin - client address - Minor address form fields changes
