ok, if it's a real small town, I get it. I went to an undergrad w/ 1000 people in small town usa bc I got a lot of scholarships and was able to graduate debt free. that part was great, but there was not a single stop light in town... and few businesses. I can easily see moving into a town like that and not being a "townie" would hurt her employment chances. Probably everyone there remembers when susie and joe went to prom and drama, drama, drama... you don't care, but they do, and thats who they hire. Their friends from HS, even if it was 30 years ago. So I can see that getting a winn-dixie job there will be tough, b/c they save those jobs for the pastor's kid or whatever.
I agree w/ the folks who suggest her taking classes there - free tuition won't help your standard of living, but might help her future prospects. IT would also open up the chance of graduate assistantships or student work positions that aren't open to non students at the school.
Another short term option is volunteering at places other than the university where you could meet people who might hire you. The local library always needs volunteers. The salvation army does too. Friends of parks/random historical marker/house/cemetery/etc (every town has one). Is there a Roatary (there or the non-hick town?) If you can meet folks there with jobs, that is a way to get to know them outside of the "I'm a newbie with all my fancy education from my non-hick town I came from" and then once they see the person, they're more likely to hire you.
