Help! Tons of business debt!

:cry:
I have $140,000 in unsecured business credit card debt. My personal credit score is strong because these credit cards (75,000, 40,000, 25,000) do not appear on my personal credit report. I have a few question since I am personally liable for these balances how long will it take for them to come after me personally? do business credit card lenders negotiate? up until now I have made timely payments but my intrest rate is going up from 0% to 17% on my 75,000 credit card!
HELP!!
