I believe you'll find that overall consensus on HN will strongly disagree with you on this point.
Here's the post most people will direct you to for an explanation of why you'll want to avoid hourly billing, and how to get to a place where you don't need to bill hourly:
For what it's worth - all of the people I know who have been able to do software-related consulting successfully over the long term don't bill hourly. They'd actually agree with you that having a minimum billable period of a week lots them lots of clients - but it lost them the clients that would try to nickel and dime them to death and complain about every invoice no matter low the hourly rate was.
It sounds like your experience has been different though, so I'm happy to hear you've found something that works for you.
