Looking for a expert in resolving html/.asp requests

Hi,
I have a program to take data from a website, my program is already resolving captcha and everything but the site that I take data from changed the request logic, they`re using .asp extension and I dont know how to pass by that requests to get the data dynamicly on the code.

If you are a expert in resolving requests, .asp, passing arguments on code to get the response back dynamically, please contact me, can pay a good amount for that.
