Will be honest with you and will possibly get some stick for it, but its advice well worth taking.
Find something else to get hooked on, save your money, buy a jet ski, become a jet ski instructor or something else, just steer well clear of Helicopters for the time being, do not under any circumstances take out a lone for training, sad truth is if you cannot afford it you cannot do it, don't try to fool yourself.
There is very little work out there, especially in the U.K or anywhere in Europe, Austraila or NZ, work in the U.S is becomming harder to come by and you get paid more working in Mcdonalds, and work in better conditions.
Your choice, but you have been warned.
