Need an automated script

I currently process about 35-40 orders a day on my website. I download all of the orders in a text file which contain the customer name, address line 1, address line 2, city, and state. I use [login to view URL] to create shipping labels and print them out. I need a script that can pull the information from the text file (spreadsheet) and insert it automatically one by one into the [login to view URL] system. Requirements: 1) The [login to view URL] system only allows for 10 labels to be created at a time. I have multiple accounts to cover all of the orders. If I need to run the script ten orders at a time, that is fine. 2) Sometimes there are bad addresses that are not accepted into the [login to view URL] system. The script must recognize when there is a bad address and mark it accordingly. 3) Bidder must visit [login to view URL], understand the system, and input a few addresses to verify whether their script will work. I have attached an example text file. The first address on the text file is a valid address, while the second address is an invalid address. The last two are valid addresses. TEST YOUR SCRIPT PRIOR TO BIDDING. I need to see an example of your work before I confirm the service provider. I will pay immediately upon verification that the script works.
