There is a nice thread on miraculous recovery on this forum
http://www.orchidboard.com/community...se-failed.html
and it has worked wonders for me when everythig else failed. May I suggest you give it a try?
be careful not to press the moss around your orchid once in the transparent container of your choice and to cover enough of its stem to allow for new roots and perhaps try to put a layer of pebbles under the moss to allow you to leave a little water at the bottom for increased humidity?
Good luck you have a great chance of succeeding!
