do some custom work on prestashop

1. SOLVE: orders do not contain products, i mean orders have no associated product. I print the invoice from the customer menu and they do not buy "nothing" the price is right. in the backoffice if i look the orders it doesnt have products.. the amount $ is correct but it seems like they doesnt bought nothing. 2. DEVELOP: I need to integrate google maps when someone register or enter their shipping address. The address "code" generated by google maps should be saved in some part of the backoffice like de order description... For what? sometimes people when writes his address writes something wrong or the name of the street is in two different locations. This make the delivery complicated. 3. MODIFY: i bought a module to export all the data of the orders to excel, this does not bring the fields a. "voucher code" (in prestashop) b. "delivery date" and "delivery time" (i bought this module called delivery days) c. "Address google maps" (module to develop in item 2)
