Build an Online Store

I need a very basic store that is able to do the following steps 1. It has to be connected to the Facebook Page 2. It has to display products in images and text in different categories 3. It should have capability to take an order (Cash on Delivery) or by Bank Transfer 3a) If someone selects Cash on Delivery additional delivery charges will be automatically added to the shipping costs 3b) If someone selects Bank Transfer the ability to post a receipt after they have made the order will be required. 4. Generate invoice and email the invoice and order details to the admin. 5. When the order is dispatched the admin can enter a tracking number. And an email is generated to the buyer. 6. The administrator can add products and the number available, Each item when the availability reaches 2 notifies the admin that only a few items are left. 7. The admin is able to change the costs of items and delivery charges. 8 . Each Item will have a category, a price, a description and a cost price. 9. The software should be able to generate a report that tells the sales/the profits/the items remaining. 10. The store has to be designed with minimalism in mind. The simpler the better.
