In your position, if you want to fly helicopters, the only sensible course of action is to try for a transfer to the AAC and do the Army Pilots Course. You'll get a fair and realistic assessment of aptitude, you'll be paid throughout, you won't have to cough up for your training and there'll be a job waiting for you at the end of it. To leave your job and seek your fortune as a self-sponsored ab initio civvy helicopter pilot in this economy is madness.
