cldutcher,
Brother head the warnings........
Triple Canopy is a top notch service. However, like previously stated, they pay the going rate to the most qualified.
Also, I can personally atest. Not all interactions between Military and Contractors oversee's are good ones. Things happen, people get hurt. Understand what you are getting into. TC has a better reputation than most, but be very cautious.
Have you looked into any other agencies? Although they are on the chopping block once again (Black Water). The last time I checked they had a training program for people in your situation (motivation/willingness, but no experience). I would at least consider this as an option. Getting your foot in the door, is always the first step.
Good Luck, be safe........and remember to duck.
cheers
