This is way too variable to estimate. Hours for the sale of a company: typically 20-2000 maybe?

For my current angel funding round, we've probably incurred somewhere around 30-50 hours of legal time.

Is there a more specific question you're driving at?

I feel misled. The number of hours I was billed (130) for a relatively straightforward sale was way higher than the estimate I was initially quoted.

I think when people were discussing this: http://www.ycombinator.com/seriesaa.html

most people were saying figures in the 25-50K range.

Incroporation - $500 to $5000 (depending on how fancy a law firm you want to have).
