Freelancing web development

Hey guys,

What is the first thing you do after given a task to develop a website for a client? Let's say, building a portal for them to organize their profiles, files etc within their society.

Let's keep it in a freelancer perspective.

Opera 9 - 10MB
IE6 - 16MB
Firefox 3.6 - 37MB
Chrome 32 - 53MB (19 + 34, two processes for a single tab, go figure)
Firefox 10  - 60MB
Pale Moon 24 - 105MB

This is for showing the EXACT SAME 8KB page with some basic HTML and 180KB of images. No advanced features, NO JS, very minimal styling. What the fuck is wrong with browser developers...?
