I think Nathan's book describes an excellent outline for success in this regard. Basically you can look into "tiers". You give away "free" resources. Blog posts and the liberally licensed open source software itself. You can also paid resources. A book, perhaps screencasts that accompany the book for a premium price. Workshops and onsite training provide another tier. At the very top is consulting at ultra-premium rates.

This is oversimplified, but this is the idea. The "free" stuff is critical, and builds the basis and "proof" for the paid offerings.
