Are there private student loans available to consolidate 30,000 dollars in high interest debt?

I have CC and car payment liabilities totaling nearly 30 grand. I would like to consolidate this debt into a low interest loan. I am a community college student with a 4.0 GPA and plan to obtain at least a bachelor's degree. My credit score is likely too low but I can possibly obtain a co-signer. Are there such loans that don't need to paid until after graduation? Who has the best interest rate??
