How do you become a credit repair specialist?

Also, how do you start a business repairing other people’s credit and restructuring their debt so they can be approved and get the best rates they can for mortgages and car loans. What about helping them with ChexSystems and to get a better hold on their credit and finances. I know the income potential is $100K a year, and also you’re helping people rebuild their lives from financial disaster so they don’t have to resort to predatory lending such as cash advances, payday loans, title loans, rent-to-own, and sub-prime mortgages (to name a few). I understand with that said its very rewarding financially and personally. Thank you for all your help.
