Gizmo, i don't believe i have the answers you want to hear so i hope you don't mind me too much. my caveat is that i know that all families are unique and is made up of individuals so ignore me if you like. to me with all the crying your dd is saying that she is not ready to be put to sleep alone in a cot. the failure in the sleep-thru methods you have tried tells me that either you don't feel, deep down that these things are right for you and your child. or that, i highly suspect to be true but what sleep training practitioners don't tell you is that you have to redo the training to some degree after any bouts of illness, teething, travel, whatever. Are you willing to do this after every change?
so what that when you get home your dd is wide awake on her dh's lap. this happened at home too the first 2 times when i went out. your dh needs to relax too and not put the emotional burden on you. my dd now can go to sleep in his arms and he is happy to cuddle her on his chest till i get home. it is bonding time.
if you want your dd to stop treating sleeptime as a hysterical event, imo you have to start to reassure her that you are always there for her. take her to bed, let her fall asleep soundly and put her back in her cot. when you go to bed and she wakes up later, go straight in to her and take her to bed with you. this is what made me keep my sanity and get some sleep as a full time teacher.
At nine months i was back at work and at the cross roads you face. I chose to co-sleep and luckily, my dh had slowly come around to that too - from the position that 'child will have to fit into our lifestyle, blah, blah, point of view.' We started by me sleeping a couple hrs or so in the spare room with dd and putting her back in her cot and slowly moving to where we are completely happy for her to be in our bed.
