Luke I have taught many pilots who have then gone on to be commercial at your age.
There is always a common problem.
You burn the hours out of sync with your stage in commercial training.
Yes everyone wants to go solo at 16 and have the license in there hands at 17. But then unless you have a serious plan of how to fund and do the commercial bit of your training you end up doing a few hours with no real plan and then stalling for lack of cash. Then when you do manage to scrape together the cash you don't have any extra to hit the training running and current.
I would advise that you hold back your training until you can fund right the way through to CPL and FI stage if that's the way you want to build hours. But even then you have to have a plan to get the IR within 2 years which you won't be able to do on a PPL instructors wage.
If you go through the forums you will find information on GAPAN and air league both of which do bursary's for young pilots.
the other thing to start on is building your CV there are 100's if not thousands of CV's out there that look exactly the same. Same hours same hobbys same everything to be honest apart from a slight variation in exam scores.
You need to start working on being different to the crowd, go push a wheelchair for some charity group, get a hobby that isn't football or reading. Try and develop your CV and get some experience which you can talk about at interview.
Unfortunately getting the blue CPL license is only the start of the process to become a commercial pilot. Getting a job can be even harder than getting the license.
