job posts do appear on these forums from time to time but i doubt it's the best place - most visitors are looking for help so are not going to be "excellent AIR developers"
there are quite a few job boards out there but i couldnt advise on a good one - an AIR developer group on linkedIn may be a good place to start
alternatively, i consider myself to be a decent developer so feel free to send me some details of your requirements (lee [at] leeburrows [dot] com)
I recommend looking at groups.adobe.com
Contact user groups or look at conferences that these developers are at. Check out 360Flex, FITC, MAX
