289587 Custom OSCommerce Cart

Need OSCommerce integration into existing site. We require a TRUE 1-page checkout. The checkout page should look exactly like the PhotoShop example image here: [login to view URL] (we'll supply all graphics) Requirements: - Direct to checkout from our landing page "Order Now" button - No "review your cart" page - No sign in/register page - No indication of OSCommerce - Everything happens dynamically on the checkout page (AJAX) - Package selection updates in Step 3 - Shipping method selection updates in Step 3 - Coupon code entry updates in Step 3 - If different shipping address is selected a new "Shipping address" section should slide down in Step 2 - When a product is selected in step 1 that option box should should have a light blue background (see example image) - Auto-ship functionality - Integrate PayPal and Google Checkout - The "Editable Region" in Step 1 should be able to contain HTML or Flash. (No border) Also we need the ability to select a product option on our landing page and have that product preselected on the checkout page. Example: If someone clicks a "Order XYZ Now" button they would be directed to the checkout with "XYZ" already selected. Otherwise, if we have a single, generic "Order Now" button on our landing page (instead of separate "Order XYZ" | "Order ABC" | "Order 123") they will be directed to the cart without any package selected.
