Few questions:
1. What are your Credit Scores? - FICO Scores preferably?
2. What is your Utilization Rate i.e. the percentage of credit owed on all cards to total of all Credit Limits?
3. What is the length of your credit history - What is the year your 1st account was opened?
4. Do you think that you are about to become unable to make your payments on time?
I hope to be able to give you a better advice once I know this information. However, bear in mind that the rate you are paying now (8.99%) APR is very low and considering that you qualify for a new card (not so sure these days even for people with good credit) with 0% APR Balance Transfer for 12 Months is not a remedy. (Besides, you will most probably have to pay Balance Transfer Fees of 3%, so it is not entirely free).
The best solution is to borrow the money from relatives or friends to pay off the balance & cut back on buying things that you can't afford.
