Gulfstream Academy does not give you a job with Continental Express!!! They offer you an interview with Gulfstream Airlines which operates as Continental Connection. When I worked for Gulfstream on the ramp, I heard about many many pilots who paid $30,000 for the training and got no job. You will be flying a Beech 1900 for $14,000 a year; you could make that much money flight instructing and not have to pay $30,000 to do it. Also, if you ever want to interview with a regional or major airline and they find out you paid for training, they'll pretty much show you the door and ask you to leave. I know a guy who had it happen to him at ExpressJet (Continental Express). There's a world of difference between Continental Express Airlines and Continental Connection operated by Gulfstream. I used to work for both companys before I started flying professionally.
You would be wiser to get a job flight instructing for six months to a year and build your time that way. I know ExpressJet hires with 600TT/100 multi, Scenic Airlines 600TT/50multi, King Airelines 500TT/50Multi and there are others.
