See a local attorney is Baton Rouge who is familiar with guardianships and conservatorships. Often time local bar associations can make referrals if you are not able to identify attorneys who have those skills required. Until there is some type of judicial intervention your grandmother's circumstances are unlikely to change.
This is a general answer only and you should seek the advice of counsel to address facts specific to your circumstances.
I agree with Attorney Hackard that the local bar association is a good place to start looking for an experienced attorney who can help you, maybe even at a reduced cost.
