Need advice

[Supersport]

Divorced. 2 kids; have them 40%. Gross income is $20,000. CS is $500/month. Student loan of $30,000; $230/month. CC debt around $4000 right now. Many cards, but most with $0 balance, and could get over $30,000 in cash advances from cards. As sad as this sounds, would it be possible to pay off student loan with cash advances (over time, say a year). Then, pay on the cards for awhile (maybe another year?). Then file chapter 7. Though my fico score is around 730, I don't care about my credit. I pay everything with cash, and have for around 8 years (no choice, after CS and student loan, don't qualify for loans). Home is owned, value around $70,000. A couple cars worth around $3000; no payments. No other assets to speak of.
