What's her credit score and history like? Has she been making the payments?
Here's what I'd do:
1. Dump it all onto the 0% card.
2. Cut up the 29% card, and use the 14% card only for emergencies. If she can't keep to that, cut it up too.
3. Pay it off aggressively.
4. Use the 9-month reprieve to find a way to consolidate your loans. Hopefully you might find something at 8-10%, or even better. Not a credit card, but more of a ... bank loan. Nine months, assuming credit score is at least somewhat decent, should be enough to find a workable solution.
Balance transfer will cost you $240. That pays for itself in less than two months!
Keep those credit cards cut up, seriously. Being able to put $300 a month towards this debt means she pretty much borrowed as much money as she possibly could to afford the minimum payment. That smacks of poor management, and poor management means cash-only.
And when I say "pay off aggressively" I mean - cancel tv, don't go out to eat, don't buy liquor, don't buy fancy food, don't buy clothes if they're not absolutely necessary, get rid of any expensive phone plans, don't drive too much... she can't afford it. Cut all expenses that aren't absolutely necessary.
