I Want to Learn Sign Language

I did some research earlier on the salary of a sign interpreter. The average is $25+ hourly. I was going to wait until I learned more about sign but I let my curiosity get the better of me. (I just had to know). Later I started to look up jobs for sign interpreters. Holy $h!+. The first thing to come up on the search was the CIA. Apparently they're short handed in the sign language department. Does anyone want to be a sign spy for the government?
