I don't know the area you live in or which ranges are close to you. This might help you find a range in your area you are unaware of.
International Defensive Pistol Association and
United States Practical Shooting Association. If you find a range near you check what classes they have to offer or they might have someone they can recommend.
To answer your question yes private lessons are worth it with the right instructor and a clear objective of what you want out of the lesson.
Good luck
