Free advise - drop the attitude.
Kids come and go on here, if you want advise then I suggest you make it as clear as possible in your first post and not expect other users to sift through your previous posts to find out.
You'll find the answer to your question here at PPRuNE using the search button.
But here goes;
PPL, FI and CPL theory will be sufficient to instruct (I'm pretty sure). If you want to get paid you'll need a CPL, you'll be limited by the weather with what I suggested but an IR will solve that.
So really you need a CPL/IR/FI if your looking to get into the airlines then ATPL exams are needed, so it would be worth sitting these exams before your CPL & IR.
Meaning to become a flexible instructor getting paid and ready for the airlines you need: ATPL's/CPL/IR/FI so basically a fATPL & FI (£45k+).
Good luck.
