Don't even bother starting with commercial pilot training.
If you can't resist and you are so desperate to start do it wherever is cheap.
But, I suggest it is not the right time to start a self sponsored route.
Best option is to wait until companies start looking for cadet pilots so if you are lucky and selected by an airline at least you will be in a safer position rather than spending all this money yourself with no promising future afterwards.
Think about it carefully and please don't only stick on my opinion.
