I went to the Golf Southern Style Academy behind Walmart also - I had never played, they were terrific - great lessons, they sell their own style of clubs (all hybrids - very forgiving!), and have a great "method" of learning to play. George is the owner; I took my lessons from Kurt, but also Chad and Wyatt are awesome!
I took lessons from the Golf Southern Style Academy which is located behind Wal*Mart on 466. My instructor was Wyatt Smith and he is terrific. My game improved by 4 or 5 strokes.
I suggest you start by going to the Sarasota Practice Center just south of the Colony Plaza Center and 466A and sign up to take some lessons. You'll know what to do from there. Good luck!
