It sounds like you have a realistic approach to things. Before switching gears, I was wondering if you have had a more recent eval by an ear specialist, to see if there is anything else that can be done for you? If so, may I suggest you look at "crime analyst" positions. I see a LOT of them listed. See link below. At the moment I'm not able to think of something applicable where you'd be out in the field more, but will come back to this if I do!
