Crossing the Chasm is a good book, but as a sales book for a freelancer?

Definitely - if you don't understand the market, the motivations for purchasing, the product development lifecycle and so on, how can you possibly sell anything beyond brute force and willpower?

If you're selling your time, you are pretty much selling 'brute force' by definition, rather than a product.
