Stick in there. Things are moving, masses of instructors are being hired by airlines. But there isn't an endless supply of instructors.
Low hours guys are getting jobs, it's just still not that common. Get out there and meet people. Don't be static. Have you flown since you passed the IR? I know it's impossible money wise but it helps massively. Also try and do a sim session a month to stay current. When an interview comes, and it will, these are all things which help massively.
Have you thought about instructing?
