In general I agree with the idea that cheap legal help that you don't know can be a waste of money or worse. However, if you know them, finding people who have the skills without the overhead can be a a significant benefit for a bootstrapping company.
I use Ryan Werner (
www.rlwerner.com). He is a college roommate (25 year ago), and has been a partner at a high-dollar San Francisco-based firm. He now is back and forth between France and the US and does most of his work remotely. He is a great guy, as well as being a smart and capable lawyer. His rate is a fraction of what you would pay for his skill level in a big firm.
