298637 Live Support Program

Hi there I have PHP Live Support source code and I was wondering if someone could modify the code to my requirements. It is really a very simple modification and I have listed it below. When people click on the Live Support icon I want a username and password field to be there and when the user types in their appropriate username and password and clicks on login then they should be directly chatting with the technical support rep. I am pretty sure this could be done right away and for a very low price. Please do let me know if you could do this and also if you could do it within my budget because I cant go over. Thanks Rahul
