If you hit the ball straight, average ~320 - 330 yds with no roll, using range balls, and equipment not necessarily made for long-ball competition - you potentially could have a career as a long driver - especially considering you've only been playing the game for a few years.
Who knows how long you'll hit the ball with a fitted driver and competition golf balls? you might easily average over 350 yards?

I haven't seen too many long driving competitions recently, but I think 350 yards wins you something.
Good luck.
