I am looking to have scripts developed (best if in PHP) for my store that would do the following:
1) Access db of my customers
2) Go to one of the Shipping sites (UPS/FedEx/USPS/DHL), the shipping site is selected based on the shipping order that customer placed
3) Login (or register automatically if customer is not registered yet) to the shipping website
4) Input all the necessary info of the sender, receiver, package details, and type of the order (for example express or ground)
5) Generate the shipping label and save it to the site's database, where a customer can access it later.
