mc sunny...
i'm sure you would enjoy being a flight instructor...part time.
i have done it for many years because like you i have another job...
at a school i taught in for many years..we a) had to have commercial licences and b)a level of knowledge above what we were teaching....thats the theory behind having the written exams done but not holding the commercial licence..but we still felt one should not just have the exams done for the CPL but also to hold the licence.
so for instructing to commercial standard we all had CPL\IR\FI with ATPL exams done....and if you have the time you'll enjoy doing the course for the CPL..and then you can charge as well for instructing..
good luck..
