Question/Dog Trainers

Good evening, everyone. Does anyone have any recommendations for a dog trainer in the central/southern Indiana area? I have a black lab that's 3 years old that has had some training, but I am needing someone to take this dog to the next level. She's an excellent retriever which isn't the problem. She has an extremely high drive, more than I am accustomed to. Any suggestions?
Thanks everyone! I appreciate it!
