I've seen people with just regular old business degrees and no work experience start out at 50-60k a year so I think you'll be fine.
Check out Boeing. Figure about 40 to start.
My ex has a bachelors in mechanical engineering and works for NASA, so i'm assuming she makes quite a bit.
In our area, they can start out at $60K to $70K, but the jobs are scarce. Probably make more money if you go to tourist areas where the building is a constant. (Vegas)
Depends on what kind of engineering, but probably around $55K.
Depending on what kind of engineering its always pretty good. My son has a few years experience and got his PE license. He gets about $100 per hour plus travel expenses.
