Convert a cookie based shop into an sql shop

I purchased your million dollar script and would like to ask you if you could help me out with some sql code. I have a webshop that works with cookies ([login to view URL]) but I do not have the time to change the cookie based cart system to a sql database system. At the moment products are chosen and saved in a cookie. When customers go to the shopping cart the price and product details are gathered from a separate file, price reductions are calculated (pretty tough calculationL )and displayed. What I would need is a pretty simple database. Password login - with email for forgotten passwords, passwords can be changed by users. Customers select products on the current website. The product number and quantity are saved in a session. This should work just like on the current website so that I can use the calculations in the current cart. Infos are separated through "|" Different artikels through "~" When customers go to the shopping cart - The items information and price will be gathered from database files through the product ID. Calculations from here should remain the same. See the current cart for details Products in the shopping cart should be able to be saved in a separate table for future shopping - just like it is possible at the moment. The next step should gather customer invoice address from the database as well as customer delivery address from the database. Separate addresses must be selectable, editable and deletable. Next – check out with review of order. No payment system at this point. After order has been sent the customer receives an email with the details of the order and the order is written to the database and the customer shopping history. Everything works so far. Only the database has to be implemented. What does not exist at all but is also very simple is a history of the previous orders. Can you do this? How much would this cost. Thanks for having a look.
