I would really hesitate to use a financial planner if your relative need more basic money management assistance. Financial planners are good for setting investment strategies but they may not be the best at helping someone figure out how to pay off debt and talk to them about setting a budget.
I have worked with community groups over the years who do credit counseling and have done a bit of lecturing on it myself and it is a different set of skills and guidelines than helping someone pick a mutual fund. I would try to find a non profit counseling agency myself.
