You have a dilema mate.
Option one involves finding a lot of money and futher money to support you when you do it. Then you have to find a job, having no practical experience of PART 145 maintenance in what possibly will be still a contracted market where more experienced mechanics will be the choice, usually..
Option two involves you finding a job when you have no maintenance experince or training whatsoever.. I do know people who have started as cleaners and have shown the willingness and attitude to be taken on as self improvers towards a mechanic level of pay. No official training and their pay goes up towards a mech after several years. I also know ex car mechanics that have been taken on in a similar manner, however with night school training towards the A or B1. These jobs are few and far between. If you don't try however you will never get..
That is the hard truth...Unfortunately
I was in military aviation for 25 years before I jumped to the industry, that was a massive advantage over your situation and I did the modules prior to leaving. It was still a culture shock to me as the RAF does do things very differently to EASA and I still have to learn the aircraft I'm involved in and do the work that was outside my field in the RAF. A Mondeo specialist can't really be expected to know a Merc when he has never worked on them, can he? Its the same for different AC types as well.
