Auto-refresh / order retrieval program for appraisal service

We need a software program which will auto-refresh an “Available Orders” screen (in Windows browser) every few seconds and detect if a new order has been posted by our client. We are competing with other vendors to be the first to respond to an available order. As soon as a new order is posted, the program must be able to read information and respond instantly in order to claim the work order. Note that another employer posted a similar request last month – we need the same functionality.
