All good things come to those that wait. I commend your decision to be cautious about entering the pay for a TR gang.
May I suggest you firstly don't put all your eggs in one basket.
Try Flybe and Loganair geographically you are perfect for both. Also put in an application for the CTC ATP wings scheme and finally whilst waiting, if you can afford 6K on a FI course will help keep your hours ticking over.
All these experiences will help you build a better CV than just paying for a TR course.
It did me and I am happy.
