Build a Website

I need custom extensions for Opencart which should work with any template. The description of the extensions are as follows:- 1. Shipping price for each manufacturer. If two products are selected from two different manufacturer then in the checkout it will add the shipping price of each manufacturer and then add it to the subtotal. And the caption may be "Delivery Charge of Manufacturer A + Manufacturer B" or Delivery Charge of Manufacturer A (Rs 90) + Manufacturer B (Rs)". In the admin of the extension I can add the price for each manufacturer and the also manage the caption of the price to be displayed. (for reference you can checkout Category & Product-Based Shipping or Ultimate Shipping extension) 2. Delivery date and time slot (am and pm) on checkout. And from the admin I can add the time slot and also select specific days of the week when the delivery is not possible. And those days cannot be selected from the frontend and also the previous dates cannot be selected. Also set some time of close of the shop after which it will not possible to select the current date. And dates can selected upto 15days from current date and that can also be controlled from the admin. 3. Store close extension. From the admin I can select the time of open and close of the shop and before or after the specified time it will prevent checkout. 4. Pincode checker for each product. So that client can check if the particular product is available on that pincode. 5. Referral extension so that if someone refer a friend he can get some reward point and the friend that joins can earn some reward point. All the extension prices should be quoted individual and also the total price. Your quotation should contain the work opencart otherwise the quotation will be discarded. You should also provide sample of your previous work on opencart extension. Thank you. HAPPY BIDDING.
