Lessons

I’ve been playing golf for about 2 years (14-16HCP) but feel like I have plateaued. It’s time to get lessons. I’m thinking maybe 5-7 lessons, one hour each plus mb 1-2 playing lessons. My ball flights are usually to the right fade/slice. With the driver, the head path comes out to in by about 5*-6* and too much spin 3500 rpm, resulting in huge loss of distance of 25-40 yards.

Question: how frequent should I schedule lessons? How many lessons or how much time, at min, should cover iron play, fairway wood, driver, short game (chipping, sand, putting) with 5-7 lessons package? Appreciate any insight and experience. TIA.
