I found the Freelance Toolkit landing page on Modern Tribe's website today thanks to a Tweet from Tom Willmot:

It's apparently been around for a while, but this was the first time I've seen it.
The toolkit is a presentation and a collection of resources for freelance web workers.
The linked resources range from videos on scope creep, to an introduction to freelancing to sample contracts, debates on hourly vs contract rates, and client communication tips.
