What makes me employable?
The simple answer is being in the right place at the right time with the right qualifications.
However having read your post here's an altogether different take on the matter....
1. Forget (for the time being) doing the CPL/FI thing.
2. Enrol on an AOPA Ground Instructor Course. - Qualify.
3. Set yourself up as an
independent PPL Ground Instructor
4. Devise a series of "products" ranging from scheduled classes to 1to1 etc. Price your "training" at a realistic level - do not try to compete on price. Your USP quality - rather than exam cramming.
5. Secure deals with hotels etc for classroom space.
6. Taking care to maintain your independent status etc market your services. (remember that the market for this stuff extends well beyond student pilots etc)
7. Be flexible and imaginative by recognising potential for "custom courses" - things like flight planning documentation - performance etc.
Once you're really established you'll know the market for FI's, hopefully have acquired a reputation as a contender - go for the FI course etc but keep the groundschool going.
All the fun of the fair but with you earning and in control....
