Arge... It sounds like really what you truly need is someone who would be willing to do a consultation with you if nothing else. Very frustrating. The hard part for me is always coming up with the money for the intake session, the cosultations and med checks are not too bad... But they have to do the intake :P
I know it is a long shot but could you try calling round to psychiatrists in private practice and seeing if anyone could do some kind of payment plan for you? The woman I got my psych eval did that for me and it was a huge help (and common, it isn't like they can't afford it). She did a lot of the interviewing via email when she had time and then we needed less face to face time. It took a bit longer but it worked out really well.
