A grocery shop in opencart - repost

I need an grocery store in open cart. The few examples of stores are [login to view URL] [login to view URL] [login to view URL] [login to view URL] [login to view URL] the look and feel is quite good of my [login to view URL] and is also build in opencart is using dropshipper theme of opencart. The ajax cart is very good of [login to view URL] and www.foodbazaarindia.com. The product display page is very simple does not refresh once added to cart or we change the category. Beside normal categories the person can also sort product by manufacturer, Say if the person is looking soap and suddenly he clicks on the logo of any manufacturer in the soap section, he shd get all the products of that manufacturer irrespective of category. The product can also be listed in multiple category by admin. Also if the products available with combos have some specific mark and once he click on that mark he shd be able to see the combo available for that product. And from there he can either add the combo to cart close the popup. There will be point system for every product purchased say one point for every rs 50 spent. The customer can accumulate that point for a bigger reward or can encash it any time by selecting various offer shown on offer page like free charge coupon selection and can redeem his point. Also I want to record the customer purchase history and wanted to send him As csv on promotional mail like 25 days after his last purchase, then on 28th day and so on as set by admin. Also I need a mobile app or wap enabled of shop like [login to view URL] the third section with specific item will come with quantity and price like ( 500 gm ghee rs. 56 etc.) and last section list will act as cart.
