How can I persue a case for Malpractice at a Florence South Carolina Hospital?

Story: My grandfather had a stroke June 2010, was in the hospital for about 4 or 5 months until he was home cared. The whole time he was in the hospital the nurses or doctors did not properly turn him every 1 to 2 hrs like they should so with this, he had developed an enormous bed sore that showed his back bone. He could have survived the stroke but the huge bed sore that was remaining on his back had got infected because it was open, he suffered from it and died January 25th 2011. My family has been trying to get the best Attorney possible to help with this situation but there is no one willing to take on the case. Because of his death I have also lost my grandmother 6 weeks later of a broken heart. They was married 52 years.
