create a website for Package Forwarding service - repost

I'm looking at starting up a package forwarding website like [login to view URL] Our company is located in Miami USA and wish to assist Latin America shoppers by allowing them to send items that are purchased in USA to our address, then we forward to their destination address. You can subscribed to viaddress to check with detail how it works, its free The website has to be in Spanish if designer doesn’t speak Spanish we can provide all translations Functioning of the page step by step 1. User enters the page to see the necessary information 2. Subscribes by filling a form with personal data, creating username and password. Page automatically generates a user number when subscribed. 3. Receive a welcoming email to the website and explaining the address and name (including user number) to use when placing a new purchase order. To finish the registration process has to do email verification process. 4. Once logged into your account there is a module to notify the orders you have placed and the packages to be expected, filling the required fields, such as tracking number, product description, quantity, price and supplier. 5. When orders arrives to the warehouse, the product manager can through a module input the User number to access the account in question and verify that the received packet corresponds to that user and so proceed to place shipping weight of the package (physical or volume, whichever is greater) and automatically place the cost of that shipment and notify via email the user account that your order has been received. 6. The user can decide whether to combine several packages to save shipping cost or to be shipped immediately. Here the user has the option to add insurance to the shipment and make payment online depending on the options available. 7. Once payment is made, the system must inform the payment has been processed correctly and that the package is ready to be sent (if possible, the system should provide the ability to print the shipping label of package and commercial invoice for custom purposes), after sending the package the admin can enter the tracking number so the user can follow the progress. 8. the system must keep a list of all subscribers data an emails in order to send massive email notifications, promotions, etc.
