There was a time in this career when you couldn't get a job, other than flight instructing, without at least 1500 hours....I don't know how the student starts are, but try flight instructing, move onto part 135 and go from there....
This career is all about timing, and while it has been terrible for a lot of people the last 10+ years, if you are only 18, then if you work hard at it you will be positioned well in the next few years as retirements kick in (due to age 65).... But....always have a back-up plan...I would not major in aviation in college, major in something else that you can use if/when furloughed....
Good luck.......
