Hi mcdady, and welcome to the forum. There's a wealth of information here to help you with your credit life.
Unless you can convert to some other type of financial instrument to pay down on the cc bal., the only way I know how is bite the bullet, withdraw the lions share of that 7k out of savings, investment and pay it down.
The CCC's are not going to lower your interest rate. Yikes! 30% on 7k. The ccc loves you! They are making a lot off of you.
(btw, withdrawing from savings was the route I went, and my scores went from 521 to 636 in 3 months time.
Good luck to you.

Never ever, ever be late. Never
