If any doubt, go fixed wing.
If you really want to fly helicopters, invest 65k and risk ending up with no job:
R22 PPL 20k (60 hours, average for getting PPL)
hour building 95 hours 27k
ATPL distant learning 3k
CAA exams 0,9k
R22 CPL 11k
Total 62k
Gives you a CPL(H) with 185 hours.
most people use hourbuilding to get an additional typerating which will increase the 27k a bit.
Some also go abroad to hour build, depending on exchange rates it can be a bit cheaper.
If you do it in a G2, then add ~15k to the bill.
Not 100% accurate figures but it's a good ballpark figure to make a plan with. Rates change during the year so make sure you have a bit more than worked out.
With just a CPL you most likely won't find much work so you either invest in a FI 12k or IR 45k,
An instructor job will give you 45 per hour, max 4 students a day so if you're busy not too bad.
IR is a huge investment and it comes down to who you know if you can get a job somewhere which onshore will start with 35k and offshore around 45-50k all depending on employer etc.
By the time you finish your training (which will take at least 1 year) things might have changed in a positive direction or in a negative direction.
Drones are more widely used in places where helicopters were used, Northsea is slowly shutting down (Compare the number of platforms 15 years ago and now).
Air ambulance, great job but salary not worth investing in an IR.
Think about what kind of job you would like and how it can impact your life (beeing away from home when you work offshore, FI hard work for minimum pay etc)
Good luck!!
Looking back, would I have gone for a fixed wing career........
