Coq Sportif,
I understand your frustration at having to wait for you first job. So many on here are in the same position as you after waiting years, but seriously think, before spending your money. Imagine waiting for that first job with even more debt, and then facing the prospect of recurrent training. A type rating is only good if you have a job to go to.
As others have said, maybe wait, the market is moving and better now. Look at the benifit of FI rating, but if you are wanting to type rate suggest you look in the back of flight International or perhaps do a search on here.
Either way best of luck
Mr W
