It is always a very difficult decision to make; that of leaving a good full-time job to become a contractor. That is when you realize what a safety net it is working for someone else. That switch though can be done right with some proper planning. The one method that I would recommend is the following one. First off we will have to assume that you have a security clearance and the appropriate experience in computer security. With that said, apply to one of the agencies that staffs positions with the government or military. There are always vacancies that need to be filled. The trick is to get a one year contract or better if available. Having that first long term contract will allow you to save up a bankroll to see you through any lean times. Remember, contract work should pay you roughly 2.5 to 3 times what your normal full-time salary is.
