EANx said: Having been there, done that, I recommend two things: 1) Operate off a retainer. Have as large or small a number as you are comfortable with but retainers are common in other professional industries, there's nothing wrong with them here. Personally, I'd start with 40 hrs and nothing less than 20. 2) Look into professional liability insurance. When you're an employee, the worst that can happen if you make a mistake is getting fired but as a consultant, you really should be familiar with terms like "interruption of business".
