Vogue, have you tried the Agudah or OU? Both offer career counseling, as far as I know. I think Young Israel might have something, also.
Do you have contacts in NY who could help you get at least enough job leads that it would be worth doing a pilot trip? Maybe friens from seminary? There are definitely a lot more options there – both in terms of jobs and of community – than it seems there are in your location. You might also be able to find a family who would give you room and board in exchange for household help and/or help with the kids.
I wish I could help you with more specifics. May Hashem send you brachah and hatzlachah in everything you do!
