Hey Mr Scouse Mouse.
I dont claim to be an expert but have experience as a flight instructor, onshore commercial pilot and currently am flying offshore in England.
i assume that you dont have an instructor rating?
if you do, are saying that you cannot get any work (not even trial lessons) as a restricted FI ?
if you dont, it will be seen from many previous threads on here that to gain a new CPL(H) only with no instructor rating (and therefore no means of increasing your hours) is hopeless.
1) you either need a CPL + IR cost around £70 k ball park, and try and get into offshore when they are hiring or:
2) get CPL + FI rating cost around £60k ball park and build your hours initially via flight instruction then onshore charter when you are a high time instructor and take it from there.
option 1 = high risk, may end in tears
option 2 = low risk, you will be flying but for less money for a while
getting a CPL with no addons whatsoever = no chance of work (unless you are a connected guy) therefore extremely high risk.
so I really think the best chance of you progressing things is to get an FI rating, hope this helps
regards
CF
