If you really want to go down that route, take a look at Canada. Several colleges and unis now offer a degree in Aviation Management or similar where you graduate after 3 years with a full CPL and seaplane ratings etc etc. Entry from age 17.
No idea as to cost but their subsequent job recruitment rates are among the best in the industry. Google Confederation College - Aviation School of Excellence in Thunder Bay to get an idea.
If they'd exisited when I was 18 I would have killed to get on such a course.
Best of luck.
