Just picking up on BPF's very reasonable point.
Any of us who are, or want to be, instructors - it's a fair question: what do we have to offer?
Are you a high ability pilot? Do you have a lot of experience on unusual types? Have you a lot of experience doing adventurous PPL type flying? Did you ace you CPL with really accurate precise flying. Have you a massive passion for aviation you want to share?
There's got to be something, some good reason to instruct, some reason why you have it in you to really offer something to new or improving pilots?
Where does a 200hr PPL, fit in that? They may, but will have to be fairly exceptional.
