What you can do is:


Use XMLHTTP to retrieve the source of the page  
Use the MSHTML object model to further automate the page


Example:
An exploration of IE browser methods, part II

What the code on this page does is:


Take advantage of XMLHTTP's speed to retrieve a webpage source faster than automating IE  
Assign the XMLHTTP response to a MSHTML Document object (effectively 'loading' the page inside the DOM), then  
Use traditional OM methods for looping through page objects, clicking buttons and so on.


At the risk of self-aggrandizement, Tim's advice is spot on. The link he provided has several methods you could use (after getting the page using XMLHTTP, of course) for either iterating through the page and clicking the "Get Estimates" button, or setting a reference to it directly and calling the HTMLInputElement.Click method.

In VBA after automated xml form post, how can I automate interaction with the response?
As a non-native speaker, I do not fully understand the meaning of the term "to become controversial" in the following text, which I have to translate into German:


  Where translators have made their presence felt they have become controversial, with those who characteristically intervene, seeking to domesticate texts, contrasted with those who foreignise, supposedly allowing other languages to alter our own.
