Immed. help for single mom in Tulsa area?

(Cross-posted. I posted in DU Lounge, too.)

Step-daughter has been living with us for most of a year and a half. Right now, one daughter is with her, other two are with their dad who plans to move out of state when divorce is final. We are at the end of what we can do to help her, and there are health issues with us, and she needs to move out this weekend -- yet she is still jobless and carless, and we are in a small town outside of Tulsa, OK, with little to no access to jobs and no access to the bus system. It seems none of the transitional homes for moms/families will even put her on their waiting list until her divorce is final, which won't be until late summer at the rate it's going. She MAY get a chunk of change from his 401K, but again not til late summer, so that means she won't have money for a car until then. The problem is this gap between NOW, when she moves out from our place, and late summer, when she could maybe get a car for better job-hunting. She doesn't want see her girls move out of state, so she desperately needs to have a stable living situation ASAP so that the girls can do their summer visits but especially so they can stay with her if they don't want to move (they don't). Her thinking right now is that she'll have to go to a day center for the homeless or something, but I don't think they'll have the resources she needs to support her in job-hunting or have her girls visit. She MIGHT be getting a job in Broken Arrow soon, which would be a God-send, but she'd have no way to get there unless she was perhaps living in Broken Arrow and could walk or get a ride from someone there.

Does anyone know of ANY place, or anybody, in Tulsa or Broken Arrow, that could help out a woman in this situation for the foreseeable future? House-sitter? A job with live-on-site benefits? Anyone looking for a job-hunting roomie with occasional visits from noisy lovable kids (ages 8-14)?
