If you are repaying a loan, it would not advisable to consider setting up a business at all. Taking up funding for a business venture and using it to repay an educational loan is the wrong idea and destined to make your business venture fail anyway. Instead, use your current work experience to move on gradually to a better paying job and then repay the loan before considering a business venture. Alternatively, look for a better paid job and start working on your business idea and look for someone who would be willing to invest funds for the business idea you have.
