The SSA, they pay interpreters on average $90 an hour for 2 hours minimum paid compensation. So even if the interpreter only interpreted for 15 minutes they'd get $180.00 for the day.
VRS at my company pays around $30-45 (depending on experience and certifications).
I got lucky. My college has a great Deaf Studies program. I am getting a Bachelor's Degree in Deaf Studies Emphasis in Interpreting - I don't think 2 years is enough school to start interpreting. Mostly because I think their should be a TON of emphasis on the Deaf culture before going into ASL and interpreting.
I'd also like to learn other forms of Sign Language eventually.
