I have come to the realization that in order to advance my game and start scoring where I want to I need coaching/lessons to tweak my swing and get it consistent. My good shots are really good, bad shots can be horribly bad. When looking for a coach/lesson giver what aspects should I be looking at. We do have a golftec in my area and I have had the tour there. What sort of prices are average for good instruction? How many lessons does it generally take to make this type of move? Are there any sites that rank/review instruction pros?
