From what I have seen over the years becoming a freelance instructor / examiner is the way to go. Instructors are two a penny; add some different skills - like being an examiner, multi ratings, etc and you stand out from the crowd. You are far better off using someone elses aircraft - be it because they are the owner or by renting from existing owners for ab intio, multi or instrument training. Of course it takes time to gain the qualifications; I appreciate you need to start some where.
