If you want to go for it be prepared!
As any heli pilot will tell you(ad nauseam)there is nothing like it.
It is very difficult to make a living as a low hour CPLH. Also you will need to budget to do an FI(R) course/FI because no-one will give you a job with 155 hrs
Currently there are way too many instructors trying to get work although I suspect that this will drop off fairly quickly.
I would recommend going to one of the larger schools(not SCabair)so that once you have got your PPL you will be able to get some cheap/Free flying doing positioning flights.
This used to be done by all the people trying to get the hours to do their AFI but now that they are out of the way the schools are dying for business.
If you are near London why not try Heliair at Denham 01895 835899
Good luck it has to be one of the most rewarding(not financially) jobs in the world
