Sign language interpreter info?

[Ruth Rogers <CRVHS_RSR@NCOCC.OHIO.GOV>]

One of our students has career plans for becoming a sign language
interpreter and she is doing a report on this career.  Our print sources
are limited and the on-line Ohio Career Information System does not have
all that she needs.  She is particularly interested in where to go for
training and salary ranges.  (She is a senior and has already had a job
offer).  Is there anywhere on the Internet that might have the type of
information she seeks?  Thanks for your assistance.
