I recently finished Priceless: The Hidden Psychology of Value by William Poundstone [1]

A number of great lessons in this, but perhaps the key one was that pricing is not as much of a 'dark art' as many of us believe. There's a good deal of scientific research into pricing successfully and profitably, which is detailed therein.

In relation to the OP, of course you need to know where to start - is $100/hour high or low for my industry and my experience? - etc. Once you have that information you can build your pricing strategy

The next step (as chopsueyar alludes to elsewhere in this discussion) is clearly communicating all of the right expectations so you do what the client wants, the client is delivered what they want, they pay you on time, and you have the choice to delight them and win loyalty and/or referrals.
