If you're building a Web 2.0 application or any website that's core to your business, then you might have to settle for simply having begun by the end of the three weeks.
For most businesses, you can have a website built very quickly. Think about the basics elements of your website, and at least get a site up with basic information about you, your business your products and your services.
Bad title, this is an article about setting up a business, not running a startup. I get the feel that articles about startups from a technical perspective tend to assume the work listed to do in these three weeks takes zero time.
Three weeks is about 13 days longer than it took for version 1.0 of my side project, for what it is worth. (Counting program, website, accounts, etc.)
I think that was probably my most productive workweek in my entire life, and it was only about 50 hours, too. (50 hours on top of the day job, which left me pretty freaking wrecked. Then again compared to some of the startups I read about I feel like I'm either a pitiful excuse for a founder or, in the alternative, merely sane.)
[I tried to roughly the same thing this summer, and get a new project out the door in 30 days. Now that was a serving of humble pie.]
